Breast cancer is the most common invasive cancer in females. It is also a leading cause of cancer deaths among females.

Breast Cancer what Is It?

Advances in screening and treatment for breast cancer have improved survival rates dramatically. Overall, the rate of breast cancer declined by about 40%Trusted Source between 1989 and 2017.

A 2019 study showed, however, that the rate in the United States may no longer be declining in women aged 20–39 years.

The American Cancer Society (ACS) reports that:

  • There are more than 3.8 million breastTrusted Source cancer survivors in the U.S.
  • The chance of dying from breast cancer is around 1 in 38 (2.6%).
  • About 281,550 new cases of invasive breast cancer will be diagnosed by the end of 2021
  • About 43,600 deaths from breast cancer are likely to occur by the end of 2021

Awareness of the symptoms and the need for screening is key in reducing the risk of mortality.

In rare instances, breast cancer can also affect males. This article will focus on breast cancer in females.

breast cancer symptoms.


The first symptom of breast cancer is usually an area of thickened tissue in the breast or a lump in the breast or an armpit.

Breast cancer develops as a result of genetic mutations or damage to DNA. These can be associated withTrusted Source exposure to estrogen, inherited genetic defects, or inherited genes that can cause cancer, such as the BRCA1 and BRCA2 genes.

When a person is healthy, their immune system attacks any abnormal DNA or growths. When a person has cancer, this does not happen.

As a result, cells within breast tissue begin to multiply uncontrollably, and they do not die as usual. This excessive cell growth forms a tumor that deprives surrounding cells of nutrients and energy.

In fact, Breast cancer usually starts in the inner lining of the milk ducts or the lobules that supply them with milk. From there, it can spread to other parts of the body.
