Is There Different Types Of Breast Cancer

Angiosarcoma Of The Breast

Are there different types of breast cancer?

Angiosarcoma is a rare form of cancer that begins in the endothelial cells, that line the blood and lymph vessels. There are two forms of angiosarcoma of the breast:

Primary angiosarcoma: This occurs in women who have never been treated for breast cancer before.

Secondary angiosarcoma: Thisoccurs in women who have already been treated for breast cancer.

In angiosarcoma, there can be necrosis, as well as hemorrhage.

What Are The Stages Of Breast Cancer

There are two different staging systems for breast cancer. One is called anatomic staging while the other is prognostic staging. The anatomic staging is defined by the areas of the body where the breast cancer is found and helps to define appropriate treatment. The prognostic staging helps medical professionals communicate how likely a patient is to be cured of the cancer assuming that all appropriate treatment is given.

The anatomic staging system is as follows:

Stage 0 breast disease is when the disease is localized to the milk ducts .

Stage I breast cancer is smaller than 2 cm across and hasn’t spread anywhere including no involvement in the lymph nodes.

Stage II breast cancer is one of the following:

  • The tumor is less than 2 cm across but has spread to the underarm lymph nodes .
  • The tumor is between 2 and 5 cm .
  • The tumor is larger than 5 cm and has not spread to the lymph nodes under the arm .

Stage III breast cancer is also called “locally advanced breast cancer.” The tumor is any size with cancerous lymph nodes that adhere to one another or to surrounding tissue . Stage IIIB breast cancer is a tumor of any size that has spread to the skin, chest wall, or internal mammary lymph nodes .

Stage IV breast cancer is defined as a tumor, regardless of size, that has spread to areas away from the breast, such as bones, lungs, liver or brain.

What Is The Most Aggressive Type Of Breast Cancer

Any breast cancer that is metastatic, or stage IV, is aggressive because it has already spread beyond the breast. Some other breast cancer types are considered more aggressive than others, including inflammatory breast cancer and triple-negative breast cancer. These may be more likely to spread, less responsive to treatment, or at higher risk of returning after treatment.

Symptoms Of Inflammatory Breast Cancer

Because the lymph channels are blocked, the breast might become:

  • swollen
  • firm or hard
  • hot to the touch

The breast can also be painful in inflammatory breast cancer, but this is not always the case.

Other possible symptoms include:

  • ridges or thickening of the skin of the breast
  • pitted skin, like orange peel
  • a lump in the breast
  • a discharge from the nipple
  • an inverted nipple the nipple is pulled into the breast

Inflammatory breast cancer symptoms can appear quite suddenly.

Inflammatory breast cancer is often confused with an infection of the breast . This is because the symptoms are very similar. Mastitis is uncommon in women who aren’t pregnant or breast feeding and it is particularly rare in women who have had their menopause.

Your doctor might give you a course of antibiotics if they think that you could have mastitis. But they will refer you to a specialist if they think you are unlikely to have an infection or if your symptoms dont clear up after antibiotics.

While inflammatory breast cancer can cause these particular symptoms, its worth being aware of the general symptoms of breast cancer.

Make an appointment to see your doctor if you notice any change in the look or feel of your breasts.

Your GP usually refers you to a breast clinic for tests.

You might have a:

  • mammogram, which is an x-ray of the breast
  • breast ultrasound
  • biopsy of the skin in the breast
  • biopsy of a breast lump
  • MRI scan of the breast

Other tests may include a CT scan or PET-CT scan, and bone scan

Chemo Drugs For Breast Cancer That Has Spread

What Are The Different Kinds Of Breast Cancer? Infographic

Although drug combinations are often used to treat early breast cancer, advanced breast cancer often is treated with single chemo drugs. Still, some combinations, such as paclitaxel plus gemcitabine, are commonly used to treat metastatic breast cancer.

For cancers that are HER2-positive, one or more drugs that target HER2 may be used with chemo.

What To Know About Breast Cancer Symptoms

The symptoms of breast cancer can vary widely and some types of breast cancer may not have any noticeable symptoms.

Sometimes a lump may be too small to be felt or to cause any changes to your breast or surrounding area. In these cases, cancerous cells are often first detected through screening techniques like a mammogram.

When there are symptoms, they can include:

  • a lump or thickening of breast tissue that you can feel with your fingers
  • breast swelling or changes to your breast size or shape
  • changes to the skin on your breast, such as dimpling, redness, or skin irritation
  • the nipple turning inward or nipple pain
  • a lump in your underarm area
  • nipple discharge other than breast milk

Its important to be familiar with how your breasts usually look and feel. This will help you notice any changes and to follow up with your healthcare professional promptly if anything looks or feels different.

Noninvasive breast cancer develops in the cells of a duct or lobule and remains in that location. Its also referred to as in situ which means in the original place.

There are two types of noninvasive breast cancer:

  • ductal carcinoma in situ
  • lobular carcinoma in situ

Lets take a closer look at each type.

Invasive Carcinoma Of No Special Type

Other names Invasive ductal carcinoma
Histopathologic types of breast cancer, with relative incidences and prognoses, with “invasive ductal carcinoma” at bottom left
Oncology, Dermatology, Breast surgery

Invasive carcinoma of no special type also known as invasive ductal carcinoma or ductal NOS and previously known as invasive ductal carcinoma, not otherwise specified is a group of breast cancers that do not have the “specific differentiating features”. Those that have these features belong to other types.

In this group are: pleomorphic carcinoma, carcinoma with osteoclast-like stromal giant cells, carcinoma with choriocarcinomatous features, and carcinoma with melanotic features. It is a diagnosis of exclusion, which means that for the diagnosis to be made all the other specific types must be ruled out.

More Information About The Tnm Staging System

The T category describes the original tumor:

  • TX means the tumor can’t be assessed.
  • T0 means there isn’t any evidence of the primary tumor.
  • Tis means the cancer is “in situ” .
  • T1, T2, T3, T4: These numbers are based on the size of the tumor and the extent to which it has grown into neighboring breast tissue. The higher the T number, the larger the tumor and/or the more it may have grown into the breast tissue.

The N category describes whether or not the cancer has reached nearby lymph nodes:

  • NX means the nearby lymph nodes can’t be assessed, for example, if they were previously removed.
  • N0 means nearby lymph nodes do not contain cancer.
  • N1, N2, N3: These numbers are based on the number of lymph nodes involved and how much cancer is found in them. The higher the N number, the greater the extent of the lymph node involvement.

The M category tells whether or not there is evidence that the cancer has traveled to other parts of the body:

  • MX means metastasis can’t be assessed.
  • M0 means there is no distant metastasis.
  • M1 means that distant metastasis is present.

Basal Type Breast Cancer

Types of Breast Cancer

Basal type breast cancer has particular genetic changes in the cells. The cells make large amounts of a protein called cytokeratin 5/6.

Basal type breast cancers are often triple negative. This means that they don’t have many receptors for oestrogen, progesterone, or HER2. So, hormone therapies and targeted drugs don’t work for most basal type cancers.

Doctors use other treatments, such as surgery, chemotherapy and radiotherapy, instead.

In Situ Breast Cancers

Ductal carcinoma in situ is the main type of in situ breast cancers. The DCIS is non-invasive breast cancer that occurs in the milk ducts, and the cells have not spread to other tissues of the breast. DCIS is treatable when identified early, though it increases the risk of developing invasive cancer. There is a possibility DCIS can reoccur after treatment, but the chances are below thirty percent. Those who have had a lumpectomy without radiation therapy have a high likelihood of having a reoccurrence. Studies have shown the therapy significantly reduces risks of reoccurrence. The American Cancer Society indicates there are over sixty thousand cases of DCIS diagnosed annually.

Although lobular carcinoma in situ is not considered cancer, it is a condition where abnormal cells develop in the milk glands and increase the risk of invasive breast cancer. In most cases, it is discovered by biopsy because it does not show any symptoms or on the mammogram. Paget disease is not common and mostly affects the nipple. It first affects the ducts of the nipple before spreading on the surface around the nipple. Some of the symptoms include itchy and inflamed skin, discharge, burning sensation, and inversion of the nipple. According to the National Cancer Institute, Paget disease is only responsible for one to four percent of breast cancer cases.

How Is Breast Cancer Diagnosed

Your health care provider may use many tools to diagnose breast cancer and figure out which type you have:

  • A physical exam, including a clinical breast exam . This involves checking for any lumps or anything else that seems unusual with the breasts and armpits.
  • A medical history
  • Breast biopsy
  • Blood chemistry tests, which measure different substances in the blood, including electrolytes, fats, proteins, glucose , and enzymes. Some of the specific blood chemistry tests include a basic metabolic panel , a comprehensive metabolic panel , and an electrolyte panel.

If these tests show that you have breast cancer, you will have tests which study the cancer cells. These tests help your provider decide which treatment would be best for you. The tests may include:

  • Genetic tests for genetic changes such as BRCA and TP53
  • HER2 test. HER2 is a protein involved with cell growth. It is on the outside of all breast cells. If your breast cancer cells have more HER2 than normal, they can grow more quickly and spread to other parts of the body.
  • An estrogen and progesterone receptor test. This test measures the amount of estrogen and progesterone receptors in cancer tissue. If there are more receptors than normal, the cancer is called estrogen and/or progesterone receptor positive. This type of breast cancer may grow more quickly.

How A Breast Cancers Stage Is Determined

Your pathology report will include information that is used to calculate the stage of the breast cancer that is, whether it is limited to one area in the breast, or it has spread to healthy tissues inside the breast or to other parts of the body. Your doctor will begin to determine this during surgery to remove the cancer and look at one or more of the underarm lymph nodes, which is where breast cancer tends to travel first. He or she also may order additional blood tests or imaging tests if there is reason to believe the cancer might have spread beyond the breast.

The breast cancer staging system, called the TNM system, is overseen by the American Joint Committee on Cancer . The AJCC is a group of cancer experts who oversee how cancer is classified and communicated. This is to ensure that all doctors and treatment facilities are describing cancer in a uniform way so that the treatment results of all people can be compared and understood.

In the past, stage number was calculated based on just three clinical characteristics, T, N, and M:

  • the size of the cancer tumor and whether or not it has grown into nearby tissue
  • whether cancer is in the lymph nodes
  • whether the cancer has spread to other parts of the body beyond the breast

Numbers or letters after T, N, and M give more details about each characteristic. Higher numbers mean the cancer is more advanced. Jump to more detailed information about the TNM system.

How Much Do Tamoxifen And Raloxifene Lower The Risk Of Breast Cancer

Breast Cancer

Multiple studies have shown that both tamoxifen and raloxifene can reduce the risk of developing estrogen receptor-positive breast cancer in healthy postmenopausal women who are at high risk of developing the disease. Tamoxifen lowered the risk by 50 percent. Raloxifene lowered the risk by 38 percent. Overall, the combined results of these studies showed that taking tamoxifen or raloxifene daily for five years reduced the risk of developing breast cancer by at least one-third. In one trial directly comparing tamoxifen with raloxifene, raloxifene was found to be slightly less effective than tamoxifen for preventing breast cancer.

Both tamoxifen and raloxifene have been approved for use to reduce the risk of developing breast cancer in women at high risk of the disease. Tamoxifen is approved for use in both premenopausal women and postmenopausal women . Raloxifene is approved for use only in postmenopausal women.

Less common but more serious side effects of tamoxifen and raloxifene include blood clots to the lungs or legs. Other serious side effects of tamoxifen are an increased risk for cataracts and endometrial cancers. Other common, less serious shared side effects of tamoxifen and raloxifene include hot flashes, night sweats, and vaginal dryness.

Feeling Unwell Or Tired

Many women do not feel as healthy after chemo as they did before. There is often a residual feeling of body pain or achiness and a mild loss of physical functioning. These changes may be very subtle and happen slowly over time.

Fatigue is another common problem for women who have received chemo. This may last a few months up to several years. It can often be helped, so its important to let your doctor or nurse know about it. Exercise, naps, and conserving energy may be recommended. If you have sleep problems, they can be treated. Sometimes fatigue can be a sign of depression, which may be helped by counseling and/or medicines.

Ductal Carcinoma In Situ

DCIS is a non-invasive cancer that is diagnosed when abnormal cells have been found in the lining of the breast milk duct. The National Breast Cancer Foundation notes that DCIS is a highly treatable cancer. Thats because it hasnt spread beyond the milk duct into any surrounding breast tissue. The American Cancer Society notes that roughly 20 percent of new breast cancer cases are instances of DCIS.

In Situ Vs Invasive Breast Cancers

The type of breast cancer can also refer to whether the cancer has spread or not. In situ breast cancer is a pre-cancer that starts in a milk duct and has not grown into the rest of the breast tissue. The term invasive breast canceris used to describe any type of breast cancer that has spread into the surrounding breast tissue.

Invasive breast cancer has spread into surrounding breast tissue. The most common types are invasive ductal carcinoma and invasive lobular carcinoma. Invasive ductal carcinoma makes up about 70-80% of all breast cancers.

What Happens After The Local Breast Cancer Treatment

Are There Different Kinds of Breast Cancer?

Following local breast cancer treatment, the treatment team will determine the likelihood that the cancer will recur outside the breast. This team usually includes a medical oncologist, a specialist trained in using medicines to treat breast cancer. The medical oncologist, who works with the surgeon, may advise the use of the drugs like tamoxifen or anastrozole or possibly chemotherapy. These treatments are used in addition to, but not in place of, local breast cancer treatment with surgery and/or radiation therapy.

After treatment for breast cancer, it is especially important for a woman to continue to do a monthly breast examination. Regular examinations will help you detect local recurrences. Early signs of recurrence can be noted in the incision area itself, the opposite breast, the axilla , or supraclavicular region .

Maintaining your follow-up schedule with your physician is also necessary so problems can be detected when treatment can be most effective. Your health care provider will also be able to answer any questions you may have about breast self-examination after the following procedures.

What Is Metaplastic Carcinoma

Also known as metaplastic breast cancer, metaplastic carcinoma is a rare type of invasive breast cancer with a unique characteristic: It contains a mix of two or more types of breast cancer cells, usually carcinoma combined with sarcoma. Metaplastic means that one form is turning into another. Various leading-edge techniques are used to analyze the exact genetics and biology of these confused cancers to find out if the tumor is more similar to carcinoma or sarcoma, since these two types of cancer have very different treatments.

Breast Cancer Is The Second Most Common Cancer Found In Women After Skin Cancer But That Doesn’t Mean Men Aren’t At Risk As Well

Whether you’re spending the day at the pool or beach or you’re just looking for a product to wear daily to protect you, sunscreen is an important part of skin care. If breast cancer is diagnosed at an early enough stage, it’s treatable. Skin cancer is by far the most common type of cancer. According to the american cancer society, just over 100,000 new cases of skin cancer are diagnosed in the united states each year. There are a number of different treatments doctors recommend. Breast cancer is the second most common cancer found in women â after skin cancer â but that doesn’t mean men aren’t at risk as well. Not only does it help prevent sunburn, but it can also help prevent skin ca. Of course, your specialist is the main person whose advice you should follow but it doesn’t do anyone harm. Skin keratosis, also known as seborrheic keratosis, are harmless, noncancerous growths that appear on the face, neck, shoulders. If you have skin cancer, it is important to know which type you have because it affects your treatment options and your outlook . Psoriasis is a skin condition that affects approximately 3% of the u.s. Skin cancer is one of the most common types of cancer. It’s characterized most commonly by the appearance of dry, thickened skin patches.
