What Is Hormone Receptor
Breast cancer tumors that are hormone receptor-positive need the hormones estrogen or progesterone to grow. Approximately 75% of breast cancers are hormone-positive in post-menopausal patients. Your healthcare provider will perform a biopsy and laboratory testing to determine the cancer type and most effective treatment.
Increased Risk Of Leukemia
Very rarely, certain chemo drugs can cause diseases of the bone marrow, such as myelodysplastic syndromes;or even acute myeloid leukemia, a cancer of white blood cells. If this happens, it is usually within 10 years after treatment. For most women, the benefits of chemo in helping prevent breast cancer from coming back or in extending life are far likely to exceed the risk of this rare but serious complication.

When Is Targeted Therapy Given
Some people have targeted therapy after surgery to reduce the chances of their breast cancer coming back.;
Sometimes targeted therapy is given before surgery to shrink a larger cancer before its removed.
Targeted therapies can also be given if breast cancer has come back or spread to another part of the body.;
How Long Does It Take To Treat Breast Cancer
After surgery, chemotherapy typically takes three to six months. However, patients with hormone-sensitive breast cancers will often be put on two to five years of hormone therapy to prevent recurrence. Of course, even early-stage breast cancer puts people at a higher risk for breast cancer. Follow-up monitoring will be a lifelong project.

Treatment : Active Surveillance
Active surveillance may be all thats needed for certain types of cancers. Your doctor may recommend this approach if the cancer is at an early stage and is growing slowly or not at all.
For example, doctors often recommend active surveillance for prostate cancer, which tends to grow very slowly. Doctors monitor patients prostate-specific antigen with blood tests and monitor symptoms. If or when symptoms worsen or tests show that the cancer is growing more rapidly, they then begin discussing additional treatments.
Often, patients who are receiving active surveillance have no symptoms and go on living their lives as usual, Batus says.
Surveillance may also be an option for patients who want a break from treatment side effects or for those who have exhausted all other treatment options.

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.

Cancer Treatment Premature Menopause And Infertility
About a quarter of the nearly 285,000 women diagnosed with breast cancer in the U.S. each year have not gone through menopause.
Some chemotherapy and hormone therapy drugs that treat breast cancer can cause permanent or temporary infertility or early menopause. Women who havenât yet gone through menopause should use birth control while having these treatments, because some chemotherapy drugs are linked with birth defects.
Chemotherapy-induced menopause happens in 10% to 50% of women younger than 40 and in 50% to 94% of women over 40. After chemotherapy, you may have months or even years of uneven ovarian function.
Radiation therapy wonât cause infertility unless it is directed at both ovaries. Depending on the type and extent of the breast cancer, your ovaries may be surgically removed or radiated to lower the amount of estrogen that your body makes. This will cause permanent infertility.
Women with breast cancer who want to start or expand a family later on should consider options to keep fertility before beginning treatment. These include:
How Is Breast Cancer Treated
Breast cancer is treated in several ways. It depends on the kind of breast cancer and how far it has spread.
Breast cancer is treated in several ways. It depends on the kind of breast cancer and how far it has spread. People with breast cancer often get more than one kind of treatment.
- Surgery. An operation where doctors cut out cancer tissue.
- Chemotherapy. Using special medicines to shrink or kill the cancer cells. The drugs can be pills you take or medicines given in your veins, or sometimes both.
- Hormonal therapy. Blocks cancer cells from getting the hormones they need to grow.
- Biological therapy. Works with your bodys immune system to help it fight cancer cells or to control side effects from other cancer treatments.
- Radiation therapy. Using high-energy rays to kill the cancer cells.
Doctors from different specialties often work together to treat breast cancer. Surgeons are doctors who perform operations. Medical oncologists are doctors who treat cancer with medicine. Radiation oncologists are doctors who treat cancer with radiation.

Types Of Targeted Therapies
There are several different types of targeted therapies available for the treatment of breast cancer.
Trastuzumab and pertuzumab are the two most common monoclonal antibodies used to treat HER2-positive breast cancer. These medications are typically administered through an IV infusion and are used in combination with chemotherapy.
After chemotherapy has finished, treatment with medications like Herceptin generally continues every 3 weeks over a total period of 1 year.
Neratinib is another type of targeted therapy, which is taken orally and is designed to help prevent the recurrence of HER2-positive breast cancer for patients whove completed 1 year of Herceptin.
Other drugs like lapatinib and tucatinib , both oral medications, and ado-trastuzumab emtansine , which is administered through an IV, are also available for the treatment of advanced HER2-positive breast cancer.
How Is Chemotherapy Given
Chemo drugs for breast cancer are typically given into a vein , either as an injection over a few minutes or as an infusion over a longer period of time. This can be done in a doctors office, infusion center, or in a hospital setting.
Often, a slightly larger and sturdier IV is required in the vein system to administer chemo. These are known as central venous catheters , central venous access devices , or central lines. They are used to put medicines, blood products, nutrients, or fluids right into your blood. They can also be used to take out blood for testing.
There are many different kinds of CVCs. The most common types are the port and the PICC line. For breast cancer patients, the central line is typically placed on the side opposite of the underarm that had lymph nodes removed for the breast cancer surgery.
Chemo is given in cycles, followed by a rest period to give you time to recover from the effects of the drugs. Cycles are most often 2 or 3 weeks long. The schedule varies depending on the drugs used. For example, with some drugs, the chemo is given only on the first day of the cycle. With others, it is given for a few days in a row, or once a week. Then, at the end of the cycle, the chemo schedule repeats to start the next cycle.
Adjuvant and neoadjuvant chemo is often given for a total of 3 to 6 months, depending on the drugs used. The length of treatment for advanced breast cancer depends on how well it is working and what side effects you have.

Most Women In The Mid
The new study looked at the 6,711 women from the trial who fell in the mid-range of 11 to 25. The goal of the study was to find out if these women could safely skip the chemotherapy.
Following surgery, the women were randomly assigned to receive chemotherapy followed by hormone therapy, or hormone therapy alone. The study was intended to measure invasive disease-free survival, the proportion of women who had not died, or had their cancer return, or developed a new cancer. Results were very similar between the 2 groups.
- Five years after treatment, the rate of invasive disease-free survival was 93.1% for those who had chemo and 92.8% for those who did not.
- Nine years after treatment, the rate of invasive disease-free survival was 84.3% for those who had chemo and 83.3% for those who did not.
Rates of overall survival were also very similar between the 2 groups.
- Five years after treatment, the rate of overall survival was 98.1% for those who had chemo and 98.0% for those who did not.
- Nine years after treatment, the rate of overall survival was 93.8% for those who had chemo and 93.9% for those who did not.

Medicines To Prevent Breast Cancer
How signicantly can breast cancer prevention drugslower a woman’s risk? Here’s a look at the numbers.
Many women who could benefit from breast cancer prevention drugs aren’t taking them.
Many new and potent medicines to prevent breast cancer have become available in the past 20 years. Surprisingly, however, many womeneven those at high risk for the diseaseare not taking advantage of these medicines.
Drugs such as tamoxifen , raloxifene , and exemestane can reduce the odds of developing breast cancer for many women at risk. “These drugs have been shown to prevent the occurrence of invasive and pre-invasive breast cancers,” says Dr. Paul Goss, director of breast cancer research at the Massachusetts General Hospital Cancer Center.
“It isn’t just cancer that’s prevented,” Dr. Goss says. “It’s precancer and abnormal mammograms. That leads to fewer biopsies. There are a lot of spin-off benefits.”
Targeted Therapy Vs Chemotherapy
Chemotherapy is a type of cancer treatment that works by killing fast-growing cells in your body to help prevent the growth and spread of cancer cells. It can be given as an oral medication or administered through an IV.
But because chemotherapy can kill both healthy and cancerous cells in your body, it can cause many side effects.
On the other hand, targeted therapy is a treatment that attacks cancer cells specifically by interfering with certain pathways that control their growth.
Unlike chemotherapy, targeted therapy is designed to only affect cancer cells, meaning that its less likely to harm the normal, healthy cells in your body. But targeted therapy pills do have side effects as well.
Furthermore, while chemotherapy kills off cancer cells that have already been produced, targeted therapy also works by preventing cancer cells from multiplying and spreading.
Targeted therapy can be administered orally or through an IV for the treatment of breast cancer. Its often used alone or in combination with other cancer treatments, including chemotherapy.

Tips To Help You Choose
Although there are some typical breast cancer treatment regimens, women do have choices.
- Talk with your doctor about all the risks and benefits of each treatment option and how they will affect your lifestyle.
- Think about joining a support group. Other people with breast cancer know what youâre going through and can give you advice and understanding. They might help you decide on a treatment, too.
- Ask your doctor whether you should join a clinical trial, a research study that tests new treatments before theyâre available to everyone.
Less Common Types Of Hormone Therapy
Some other types of hormone therapy that were used more often in the past, but are rarely given now include:
- Megestrol acetate , a progesterone-like drug
- High doses of estrogen
These might be options if other forms of hormone therapy are no longer working, but they can often cause side effects.

What Are The Types Of Breast Cancer Treatment
Surgery. For most people, the first step is to take out the tumor. An operation called lumpectomy removes only the part of your breast that has cancer. Itâs sometimes called breast-conserving surgery. In a mastectomy, doctors remove the whole breast. There are different types of mastectomies and lumpectomies.
Radiation therapy. This treatment uses high-energy waves to kill cancer cells. Most women under age 70 who have a lumpectomy get radiation, too. Doctors also might recommend this method if the disease has spread. It helps destroy any cancer cells that the surgeon couldnât remove. Radiation can come from a machine outside your body, or you might have tiny seeds that give off radiation placed inside your breast where the tumor was.
Other treatments destroy or control cancer cells all over your body:
Chemotherapy uses drugs to kill cancer cells. You take the medicines as pills or through an IV. Most people get it after surgery to kill any cancer cells left behind. Doctors also prescribe it before surgery to make tumors smaller. Chemo works well against cancer, but it also can harm healthy cells.
Immunotherapy uses your own immune system to target cancer. The drugs atezolizumab and sacituzumab govitecan-hziy have been approved to treat triple-negative breast cancer that has spread.
Selective Estrogen Receptor Modulators
Tamoxifen is the most common first-line treatment for hormone-sensitive breast cancer. Taken for two to five years following surgery, tamoxifen significantly reduces recurrence and mortality. As a selective estrogen receptor modulator, tamoxifen and other drugs such as toremifene and raloxifene slow down tumor growth by preventing estrogen from attaching to tumor cells. However, these drugs do not block estrogens effects on other tissues in the body. Both tamoxifen and raloxifene are also FDA-approved to prevent breast cancer in high-risk women.

What Is Breast Cancer
Breast cancer is a common cancer of the breast tissues; about 270,000 women in the United States were diagnosed with breast cancer this year. Breast cancer can begin in any of the breast tissues: milk glands , ducts, or the connective tissue that holds the breast together and attaches it to the chest wall.
Breast cancer most often begins in the lobules or ducts. Cancer can spread to other parts of the breast or body through tissue fluid or the bloodstream.
Breast cancer has several types:
Treatment will depend not only on the type of breast cancer but on the stage of cancer. Stages of breast cancer represent how extensively cancer has grown and spread. Early-stage breast cancer is localized and contained. Middle-stage breast cancers have spread to surrounding lymph nodes and other tissues in the breast. Advanced or metastasized breast cancer has spread to other parts of the body. As the cancer advances, treatment becomes more difficult and survival rates go down.
Alternative To Chemotherapy And Radiation Cancer Treatments
So, what can you do instead of conventional cancer treatment? Today, there are a host of substitute therapies and alternative medicine options to chemo and radiation therapy that fall under the umbrella of alternative cancer treatments. But, as a note, these cancer care alternatives should not be confused with stress-relieving therapies such as acupuncture, massage, tai chi, yoga, meditation, etc.
Whether youre exploring prostate cancer natural treatment options, a lymphoma natural treatment or are in search of alternative treatment for ovarian cancer, finding the right alternative treatments involves a customized and targeted therapy plan that relies upon utilizing the patients immune system to help stave off cancer. Whereas chemo completely wrecks the immune system for a cancer patient, alternative treatments are intended to:
- Train the immune system to specifically attack cancer cells.
- Stimulate the immune system to work better, faster, smarter, stronger in attacking cancer cells.
- Provide the patient with immune system components or man-made immune supplements to bolster your defense network.
As with traditional cancer treatments, alternative therapies may work better for certain strains or cases of cancer than others.
