Breast cancer – Symptoms and causes / Article
Breast cancer is the cancer that forms in the cells of the breasts.
After skin cancer, breast cancer is the most common cancer in women in the United States. Breast cancer can occur in both men and women, but it is far more common in women.
Breast cancer awareness and plentiful support for research funding have led to advances in the diagnosis and treatment of breast cancer. Breast cancer survival rates have increased, and the number of deaths associated with the disease is steadily declining, mainly due to factors such as earlier detection, a new personalized approach to treatment, and a better understanding of the disease.

Doctors know that breast cancer occurs when some breast cells start growing abnormally. These cells divide more rapidly than healthy cells and continue to form a lump or mass. Cells can spread through your breast to your lymph nodes or other parts of your body.
Breast cancer begins with cells in most milk-producing ducts (invasive ductal carcinoma). Breast cancer can also begin in glandular tissues called lobules (invasive lobular carcinoma) or in other cells or tissue within the breast.
Researchers have identified hormonal, lifestyle and environmental factors that may increase your risk of breast cancer. But it is not clear that some people who have no risk factors develop cancer, yet others at risk never do so. It is likely that breast cancer is caused by a complex interaction of your genetic makeup and your environment.
