The Deadly Breast Cancer Risk For Black Women

Lung cancer was the leading cause of cancer death, accounting for 23% of all cancer deaths. Other common causes of cancer death were cancers of the colon and rectum , pancreas , female breast , prostate , and liver and intrahepatic bile duct . Other cancers individually accounted for less than 5% of cancer deaths.

In 2019

  • 139,603 people died of lung cancer .
  • 51,896 people died of colorectal cancer .
  • 45,886 people died of pancreatic cancer .
  • 42,281 females died of breast cancer.

Researchers Create A Potential Therapy For Deadly Breast Cancer That Has Few Treatment Options

  • New York, NY

Mount Sinai researchers have designed an innovative experimental therapy that may be able to stop the growth of triple-negative breast cancer, the deadliest type of breast cancer, which has few effective treatment options, according to a study published in Nature Chemical Biology in December.

The therapy is known is MS1943. In a cancer cell line and mouse models, it degraded a protein called EZH2 that drives the growth of triple-negative breast cancer.

Research teams led by Jian Jin, PhD, Director of the Mount Sinai Center for Therapeutics Discovery, and Ramon Parsons, MD, PhD, Director of The Tisch Cancer Institute at Mount Sinai, developed MS1943 as a first-in-class small-molecule agent that selectively degrades EZH2. They also showed that agents that inhibit the enzymatic activity of EZH2 but do not degrade EZH2 did not work in triple-negative breast cancer.

MS1943 effectively reduced EZH2 protein levels in a variety of cancer cell lines, including a triple-negative breast cancer cell line, leading to the death of these triple-negative breast cancer cells.

This research was supported in part by the grants R01CA230854 and R01CA218600 from the U.S. National Institutes of Health.

Cytotoxics And Targeted Therapies

are a relatively new class of cancer drugs that can overcome many of the issues seen with the use of cytotoxics. They are divided into two groups: small molecule and antibodies. The massive toxicity seen with the use of cytotoxics is due to the lack of cell specificity of the drugs. They will kill any rapidly dividing cell, tumor or normal. Targeted therapies are designed to affect cellular proteins or processes that are utilised by the cancer cells. This allows a high dose to cancer tissues with a relatively low dose to other tissues. Although the are often less severe than that seen of cytotoxic chemotherapeutics, life-threatening effects can occur. Initially, the targeted therapeutics were supposed to be solely selective for one protein. Now it is clear that there is often a range of protein targets that the drug can bind. An example target for targeted therapy is the BCR-ABL1 protein produced from the , a genetic lesion found commonly in and in some patients with . This has enzyme activity that can be inhibited by , a drug.

What Is The Survival Rate By Stage For Triple Negative Breast Cancer

Survival rates are a way to discuss the prognosis and outlook of a cancer diagnosis. The number most frequently mentioned is 5-year survival. Many patients live much longer, and some die earlier from causes other than breast cancer. With constant change and improvement in therapies, these numbers also change. Current 5-year survival statistics are based on patients who were diagnosed at least 5 years ago and may have received different therapies than are available today.

Below are the statistics from the National Cancer Institute’s SEER database for the survival of all patients with breast cancer, by tumor stage:

Why Is There No Cure

Top 6 Deadliest Types of Cancer

During most of the 20th century, the number of people killed by cancer every year relative to population size, or the cancer death rate rose steadily to its peak in 1991, according to the ACS’s most recent summary of the state of cancer in the U.S. Since 1991, the cancer death rate has fallen by 31%, which is equivalent to 3.2 million fewer cancer deaths compared with the death rate in 1991.

The study authors attribute the decrease in cancer death rates to reductions in smoking, earlier detection and better treatments for some cancers. “We have made a lot of progress in the fight against cancer,” Siegel said.

Yet despite all that progress, a wholesale “cure for cancer” remains elusive for many reasons. The first issue is that cancer is not just one disease that could be eradicated with one cure. Instead, it’s hundreds of diseases, Siegel explained. “We would need hundreds of different types of cures to cure all cancer,” she said.

Another reason it’s hard to cure cancer is that the bar for cancer being cured is incredibly high. Cancer is cured if there are no traces of it in the body and it will never come back, according to the NCI, or is not expected to come back, according to the ACS. But even when all traces of a cancer have disappeared, there’s no way of knowing with certainty that it won’t return.

Is Infiltrating Ductal Carcinoma Curable

4.3/5Ductal Carcinomacancertreatableread here

All together, invasive ductal carcinoma refers to cancer that has broken through the wall of the milk duct and begun to invade the tissues of the breast. Over time, invasive ductal carcinoma can spread to the lymph nodes and possibly to other areas of the body. Invasive ductal carcinoma also affects men.

Beside above, what stage is invasive ductal carcinoma? Specifically, the invasive ductal carcinoma stages are: Stage 1 A breast tumor is smaller than 2 centimeters in diameter and the cancer has not spread beyond the breast. Stage 2 A breast tumor measures 2 to 4 centimeters in diameter or cancerous cells have spread to the lymph nodes in the underarm area.

Secondly, what is the treatment for infiltrating ductal carcinoma?

Treatments for invasive ductal carcinoma include surgery, chemotherapy, radiation therapy, hormonal therapy, and targeted therapy. You and your doctor will decide what treatment or combination of treatments is right for you depending on the characteristics of the cancer and your personal preferences.

Is chemo necessary for invasive ductal carcinoma?

An entire course of chemotherapy usually takes approximately three to six months to complete, and can be repeated as necessary. Invasive ductal carcinoma chemotherapy can be effective for treating many types of breast cancer, including: Triple negative breast cancer. HER2/neu-positive breast cancer.

Treatment For Invasive Breast Cancer

Treatment for invasive breast cancer usually involves some combination of surgery, radiation therapy, chemotherapy, hormone therapy and/or HER2-targeted therapy.

The order of therapies and the specific treatments depend on the cancer stage and the characteristics of the tumor .

Americans Cancer Concerns Misaligned With Mortality Rates

What types of cancer are the deadliest? According to the American Cancer Society, lung cancer and lung cancer caused by asbestos is the number one killer, with 142,670 estimated deaths in 2019 alone, making it three times deadlier than breast cancer. Despite this, only 14% of respondents said they were most concerned about lung cancer.

The second and third deadliest cancers are colorectal cancer and pancreatic cancer, respectively. Breast cancer, which will claim an estimated 42,260 lives in 2019, is the fourth deadliest.

According to these figures, breast cancer, which has a much smaller mortality rate compared to lung or colon cancer, is the one Americans fear and support the most.

What the nonprofit, Susan G. Komen is doing to tackle the deadliest stage of breast cancer

Although there are known risk factors for the development of any kind of breast cancer, doctors do not understand the exact cause of breast cancer.

  • Normal cells become cancer cells due to changes or mutations in the DNA.
  • While people inherit some DNA changes, others acquire these DNA changes during a person’s life.

The following are causes and risk factors for any type of breast cancer, including triple-negative breast cancer:

  • Increasing age

What Is Stage I

Stage I is the earliest point of invasive cancer when tumor cells have started to spread to surrounding, normal breast tissue, Cruz said. In this stage the spread is contained to a small area.

Stage I is divided into categories IA and IB based on the size of a tumor and where cancer cells are detected. In IA, the tumor is about the size of a grape, Cruz said. Stage IB indicates the tumor is smaller or nonexistent, but there are small clusters of cells in the lymph nodes.

How Does Erso Work

Study authors explain that the drug relies on a protein called the estrogen receptor. When ErSO binds to this protein, it starts regulating the pathway in cells that preps cancer cells for growth and protects them from stress. The pathway, called the anticipatory Unfolded Protein Response , drives the production of proteins that protects cancer cells from damage.

The a-UPR is already on, but running at a low level, in many breast cancer cells, Shapiro explains. It turns out that this pathway shields cancer cells from being killed off by anti-cancer drugs.

Because this pathway is already on in cancer cells, its easy for us to overactivate it, to switch the breast cancer cells into lethal mode, adds graduate student and first author Darjan Duraki.

Examples Of Rates Versus Numbers

Say, town A has a population of 100,000 and town B has a population of 1,000. Over a year, say there are 100 breast cancer deaths in town A and 100 breast cancer deaths in town B.

The number of breast cancer deaths in each town is the same. However, many more people live in town A than live in town B. So, the mortality rates are quite different.

In town A, there were 10 breast cancer deaths among 100,000 people. This means the mortality rate was less than 1 percent .

In town B, the mortality rate was 10 percent .

Although the number of deaths was the same in town A and town B, the mortality rate was much higher in town B than in town A .

Lets look at another example. In 2021, its estimated among women there will be :

  • 100 breast cancer deaths in Washington, D.C.
  • 720 breast cancer deaths in Alabama
  • 4,730 breast cancer deaths in California

Of the 3, California has the highest number of breast cancers. However, that doesnt mean it has the highest breast cancer rate. These numbers dont take into account the number of women who live in each state. Fewer women live in Alabama and Washington, D.C. than live in California.

Other factors may vary by state as well, such as the age and race/ethnicity of women. So, to compare breast cancer mortality rates, we need to look at mortality rates.

In 2021, the estimated mortality rates are :

  • 26 per 100,000 women in Washington, D.C.
  • 22 per 100,000 women in Alabama 22
  • 19 per 100,000 women in California 20

Liver And Intrahepatic Bile Duct Cancer 5

A Closer Look at the Top 5 Deadliest Cancers

Liver cancer is one of the most common forms of cancer worldwide. Though liver cancer is uncommon in the United States, it has been on the rise, with liver cancer incidence in the U.S. more than tripling since the 1980s, according to the ACS.

The most significant risk factor for liver cancer is chronic hepatitis B or hepatitis C infections, according to the ACS. Both of these infections are transmitted through bodily fluids, including blood and semen. The CDC recommendations that all children be vaccinated against hepatitis B virus, but there is no vaccine for hepatitis C, according to the ACS.

A closely related cancer is intrahepatic bile duct cancer, which occurs in the ducts that carry bile from the liver and gallbladder to the small intestine, where the bile helps digest fats from food, according to the ACS. The NCI estimates that in 2021, approximately 30,230 Americans will die from liver and intrahepatic bile duct cancer.

The Emerging Concept Of Triple Negative Breast Cancer

Breast cancers are commonly associated with a high incidence and a high mortality rate in the female population worldwide. However, at a microscopic and molecular level, breast cancer is not a homogeneous disease, thus being the focus of numerous ongoing studies. The molecular heterogeneity of the normal breast tissue has been previously documented and has outlined the different molecular profiles of epithelial and non-epithelial cells responsible for the existence of several molecular types of breast carcinomas, already characterized . Starting from the histopathological classification up to the molecular classification, breast cancer has been constantly redefined in order to ensure a better management of the patient. In 2012 Boyle et al. stated that the minimal characterization of breast cancer was a situation that had lasted for a century, until a quiet revolution has taken place so that in modern times breast cancer is characterized by its molecular and clinical heterogeneity .

Differences By Race And Ethnicity

Some variations in breast cancer can be seen between racial and ethnic groups. For example,

  • The median age of diagnosis is slightly younger for Black women compared to White women 63 years old).
  • Black women have the highest death rate from breast cancer. This is thought to be partially because about 1 in 5 Black women with breast cancer have triple-negative breast cancer – more than any other racial/ethnic group.
  • Black women have a higher chance of developing breast cancer before the age of 40 than White women.
  • At every age, Black women are more likely to die from breast cancer than any other race or ethnic group.
  • White and Asian/Pacific Islander women are more likely to be diagnosed with localized breast cancer than Black, Hispanic, and American Indian/Alaska Native women.
  • Asian/Pacific Islanders have the lowest death rate from breast cancer.
  • American Indian/Alaska Natives have the lowest rates of developing breast cancer.

How Common Is Breast Cancer

The Deadly Breast Cancer Risk For Black Women

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.

What Is Stage Iii

“In this stage, I tell my patients the real war against the cancer begins,” Cruz said. “Spreading is much more advanced.”

According to Cruz, stage III is unique in that it has three subcategories: IIIA, IIIB and IIIC.

IIIA has tumors all larger than five millimeters and has spread to lymph nodes. Cruz said the higher number of lymph nodes with cancer cells, the more advanced it is.

In stage IIIB, the tumor has spread to the chest wall and skin of the breast. In many cases, this spreading can result in swelling or ulcers. The cancer cells have also spread to nine lymph nodes.

There is advanced spreading in stage IIIC: the cancer has spread to the chest wall, skin of the breast, 10 or more lymph nodes and the collarbone.

“In stage III, yes there is advanced spreading. Yes it is harder to treat, but not untreatable,” Cruz said. “That’s what we tell our patients, although the spreading is scary, we can still fight it.”
