Trends In Breast Cancer Deaths
Breast cancer is the second leading cause of cancer death in women. The chance that a woman will die from breast cancer is about 1 in 39 .
Since 2007, breast cancer death rates have been steady in women younger than 50, but have continued to decrease in older women. From 2013 to 2018, the death rate went down by 1% per year.
These decreases are believed to be the result of finding breast cancer earlier through screening and increased awareness, as well as better treatments.
How Do Tamoxifen Raloxifene Anastrozole And Exemestane Reduce The Risk Of Breast Cancer
If you are at increased risk for developing breast cancer, four medications tamoxifen , raloxifene , anastrozole , and exemestane may help reduce your risk of developing this disease. These medications act only to reduce the risk of a specific type of breast cancer called estrogen receptor-positive breast cancer. This type of breast cancer accounts for about two-thirds of all breast cancers.
Tamoxifen and raloxifene are in a class of drugs called selective estrogen receptor modulators . These drugs work by blocking the effects of estrogen in breast tissue by attaching to estrogen receptors in breast cells. Because SERMs bind to receptors, estrogen is blocked from binding. Estrogen is the fuel that makes most breast cancer cells grow. Blocking estrogen prevents estrogen from triggering the development of estrogen-receptor-positive breast cancer.
Anastrozole and exemestane are in a class of drugs called aromatase inhibitors . These drugs work by blocking the production of estrogen. Aromatase inhibitors do this by blocking the activity of an enzyme called aromatase, which is needed to make estrogen.
Changing The Surgical Game
1960s and 70s: American surgeon Bernard Fisher believed that cancer cells spread through the body via the blood and lymph system much earlier than previously thought. He proved that lumpectomy followed by radiation or chemotherapy was just as effective as a radical mastectomy in early-stage breast cancer.
Science says: Despite similar survival rates for the lumpectomy and radical mastectomy, more women are now opting for the later as a preventative measurerates have tripled since 1998, one study found.

The Father Of The Hormonal Theory
1896: Thomas Beatson, a British doctor, reported that two patients with metastatic breast cancer seemed to go into remission after he surgically removed their ovaries. The reason? He believed that the hormones being secreted by the ovaries could spur the growth of cancer.
Science says: He wasnt right, but having a family history of either breast or ovarian cancer raises your risk for getting these diseases. The common denominator: genetic mutations, most often in the BRCA1 and BRCA2 genes.
Breast Cancer Treatments In The 21st Century
Breast cancer treatment is becoming more personalized as doctors learn more about the disease.
Its now seen as a disease with subtypes that have different patterns and ways of acting on the body. The ability to isolate specific genes and classify breast cancer is the beginning of more-tailored treatment options.
Special tests can also tell doctors more about breast cancer.
For example, the Oncotype DX gene profile test can examine part of a tumor to find out which genes are active in it.
Doctors can determine which patients with early stage breast cancer can be treated with antiestrogen therapy alone, and who would need the addition of chemotherapy.

How Common Is Breast Cancer
Breast cancer is the most common cancer in women in the United States, except for skin cancers. It is about 30% of all new female cancers each year.
The American Cancer Society’s estimates for breast cancer in the United States for 2021 are:
- About 281,550 new cases of invasive breast cancer will be diagnosed in women.
- About 49,290 new cases of ductal carcinoma in situ will be diagnosed.
- About 43,600 women will die from breast cancer.
Breast cancer mainly occurs in middle-aged and older women. The median age at the time of breast cancer diagnosis is 62. This means half of the women who developed breast cancer are 62 years of age or younger when they are diagnosed. A very small number of women diagnosed with breast cancer are younger than 45.
Finding Out How Cancer Spreads
People still couldn’t figure out how cancer got from one part of the body to another. Some people thought cancer spread because of trauma or parasites. Other people said cancer spread in the body “like a liquid.”
A German surgeon named Karl Thiersch was the first person to prove that cancer spread through malignant cells.
While a lot of progress was made in understanding cancer, there were also some missteps along the way. In 1926, a Nobel Prize was wrongfully awarded for the discovery of the cause of stomach cancera worm.

Can People With Breast Cancer Get A Covid
Yes, the three COVID-19 vaccines available in the United States are considered safe and effective for people receiving treatment for cancer and with a history of cancer in most cases. The CDC, the National Comprehensive Cancer Network , and other expert medical groups have recommended that people receiving treatment for cancer should be vaccinated. Still, everyones situation is different, and you should talk with your doctor about getting vaccinated and whether and how many boosters you should get if you are fully vaccinated.
Breast Cancer In Ancient Egypt
The first mention of cancer of any kind was a case of breast cancer documented in Egypt around 1600 BC. The Edwin Smith Papyrus, an ancient text found in 1860 in an Egyptian tomb, described eight cases of tumors or ulcers of the breast. The first doctors attempting to treat breast cancer wrote of the mysterious disease: There is no treatment!

Natural Ancient Remedies For Breast Cancer
Early remedies for breast cancer were aimed at offering temporary relief or prolonging life rather than attempting to cure the disease. The Egyptian Edwin Smith Papyrus echoed a sentiment which lasted many centuries when it pronounced: There is no treatment. Surgery was therefore generally avoided as futile and various herbal medicines or ointments preferred.
Common treatments used throughout history when treating breast cancer include:
- Purging of humors
- Prayers and rites to the Gods
- Opium
Lessons From The History Of Surgery In Breast Cancer
There are three lessons to be gained from the history of surgery in breast cancer. First, to delve into history is to rediscover buried insights: Galens perceptive assessment that breast cancer is a systemic disease was echoed two millennia later in Fishers 20th century observations. Second, the evolution of therapeutic weaponry raises the fortunes of medical disciplines or minimises their supremacy as stand-alone choices for panacea or cure . Third, stooping to conquer is the mark of survival in contemporary medical practice. Surgery has won the day by adapting and playing a complementary role in modern cancer management as a stylised, scientific and patient-friendly craft.

Nineteenth Century: The Golden Age Of Surgery
The surgical discipline rapidly grew on the bedrock of a spate of discoveries that rendered it safer with a good outcome for the patient. Disinfection and sterilisation and the use of sterile gloves were the first landmark events. General anaesthesia revolutionised the surgeons ease . Although in 1818 James Blundell attempted blood transfusion in postpartum haemorrhage, safe transfusions would be achieved only at the dawn of the 20th century with the discovery of blood groups by Karl Landsteiner. Against this background, seminal contributions to cancer came from the microscopic identification of normal cells and their cancerous brethren all the way from Hooke in 17th century England to Müller and Virchow in 19th century Germany. Müller dismissed the humoral theory of the origin of cancer, declaring that cancers were composed of living cells and suggesting that metastasis was due to spread of these cells. The demonstration that breast cancer spread along the lymphatics to the guardian axillary nodes was to form the basis of a variety of excision techniques. Unique forms of spread leading to the clinical manifestations of carcinoma en cuirasse or peau dorange and Pagets disease would demand alternative ways of approaching treatment.
A Brief History Of Metastatic Breast Cancer
by Health Writer
Nowadays, we hear breast cancer and we think pink ribbons and racing for the cure, as if the disease belongs only to the modern era. But medical pros have been trying to treat metastatic breast cancer for millennia. Throughout the ages, there have been real advances, as well as tons of weird theories that actually harmed women more than helped them. Still, weve come a long way. Serious scientific breakthroughs can help those with MBC live longer, healthier lives. Take a walk through historyand look at where we’re at now with MBC.

The First Documented Case Of Cancer
The world’s oldest documented case of cancer was found on papers from ancient Egypt in 1500 BC. It talked about a tumor found in the breast. The cancer was treated by destroying the tissue with a hot instrument called “the fire drill.” Today, we call this “cauterization.”
Some writings have shown that the ancient Egyptians could tell the difference between cancerous and noncancerous tumors. For example, surface tumors were taken out with surgery much like they are today.
Looking Inside The Body
After a person dies, a doctor called a pathologist can look inside the body at all the organs. This is called an autopsy.
In 1628, a doctor named William Harvey started doing autopsies to learn more about what the body looked like on the inside. It also helped scientists figure out what each organ did. For example, when blood circulation was discovered, it opened the door for more research on different diseases.
In 1761, Giovanni Morgagni of Padua did the first autopsy to find out why someone died. We still do autopsies for this reason today.

The First Modern Breast Cancer Treatments
Modern breast cancer treatments only became commonplace once
- Scientists began to establish the relationship between breast cancer and genesA sequence in the DNA which can be passed down from parent to child. Genes helps determine physical and functional traits for the body.
- Surgeons started viewing breast cancer as a localized disease which could be removed before it spreads
Both of these theories meant shifting away from beliefs about breast cancer relating to bodily fluids, viral contagion or sexual psychology. It now meant that breast cancer could be treated by isolating specific cells or removing affected areas the beginning of the treatment known today as the mastectomyAn operation removing all or part of the breast..
Around the 1750s a number of surgeons, including Jean Louis Petit, Henri Le Dran, Claude-Nicolas Le Cat and Benjamin Bell, began performing breast cancer surgery removing lymph nodesSmall, bean-shaped collections of immune tissue that filter out cell fluid and bacteria that may be circulating in the body. They help fight infections and play a role in fighting cancer. and underlying muscle along with breast tissue.

How Much Do Anastrozole And Exemestane Lower The Risk Of Breast Cancer
Studies have shown that both anastrozole and exemestane can lower the risk of breast cancer in postmenopausal women who are at increased risk of the disease.
In one large study, taking anastrozole for five years lowered the risk of developing estrogen receptor-positive breast cancer by 53 percent. In another study, taking exemestane for three years lowered the risk of developing estrogen receptor-positive breast cancer by 65 percent.
The most common side effects seen with anastrazole and exemestane are joint pains, decreased bone density, and symptoms of menopause .

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.

Renaissance: A Celebration Of Arts And The Emergence Of Surgery
The 16th to 18th centuries not only bred artistic creativity but proved to be the golden age for the emergence of surgery. The craft of surgery was unshackled from its previous conjoint status with the barbers trade and grew on the shoulders of a strong anatomical exploration of the human body by Andreas Vesalius in 16th century Belgium. In 18th century England and France, respectively, Coopers eponymous ligaments of the breast and Sappeys subareolar plexus of lymphatics ushered in an era that revisited the origins and spread of breast cancer., In the same era, John Hunter replaced black bile with lymph as the cause of breast cancer. A multitude of theories ranging from inspissated milk, trauma, personality type, exposure to air and infection were fed into the cauldron of carcinogenesis. The observation of the disease within families was naturally attributed to infection. Amidst this chaotic search for the truth, accounts of heroic surgeries from simple lumpectomies to radical removal of the pectoralis, enliven medical records. These are rendered more vivid and admirable when it is recalled that in the absence of anaesthesia, skill and speed were the sole attributes of a successful surgeon. It is also a grim reminder that surgery was the solitary modality for hope of relief with anecdotal incidences of cure. More conservative compatriots used ligatures or lead plates to strangulate the tumours, preferring them to the horrors of breast amputation.
How Is Breast Cancer Diagnosed
During your regular physical examination, your doctor will take a thorough personal and family medical history. He or she will also perform and/or order one or more of the following:
- Breast examination: During the breast exam, the doctor will carefully feel the lump and the tissue around it. Breast cancer usually feels different than benign lumps.
- Digital mammography: An X-ray test of the breast can give important information about a breast lump. This is an X-ray image of the breast and is digitally recorded into a computer rather than on a film. This is generally the standard of care .
- Ultrasonography: This test uses sound waves to detect the character of a breast lump whether it is a fluid-filled cyst or a solid mass . This may be performed along with the mammogram.
Based on the results of these tests, your doctor may or may not request a biopsy to get a sample of the breast mass cells or tissue. Biopsies are performed using surgery or needles.
After the sample is removed, it is sent to a lab for testing. A pathologist a doctor who specializes in diagnosing abnormal tissue changes views the sample under a microscope and looks for abnormal cell shapes or growth patterns. When cancer is present, the pathologist can tell what kind of cancer it is and whether it has spread beyond the ducts or lobules .
