Cancer is a broad term for a class of diseases characterized by abnormal cells that grow and invade healthy cells in the body. Breast cancer starts in the cells of the breast as a group of cancer cells that can then invade surrounding tissues or spread (metastasize) to other areas of the breast
When you’re told that you have breast cancer, it’s natural to wonder what may have caused the disease. But no one knows the exact causes of breast cancer. Doctors seldom know why one woman develops breast cancer and another doesn’t, and most women who have breast cancer will never be able to pinpoint an exact cause. What we do know is that breast cancer is always caused by damage to a cell’s DNA. See diagram here.
Cancer begins in the cells which are the basic building blocks that make up tissue. Tissue is found in the breast and other parts of the body. Sometimes, the process of cell growth goes wrong and new cells form when the body doesn’t need them and old or damaged cells do not die as they should. When this occurs, a buildup of cells often forms a mass of tissue called a lump, growth, or tumor. Breast cancer occurs when malignant tumors develop in the breast. These cells can spread by breaking away from the original tumor and entering blood vessels or lymph vessels, which branch into tissues throughout the body. When cancer cells travel to other parts of the body and begin damaging other tissues and organs, the process is called metastasis.
Every person should know the symptoms and signs of breast cancer, and any time an abnormality is discovered, it should be investigated by a healthcare professional.
Most people who have breast cancer symptoms and signs will initially notice only one or two, and the presence of these symptoms and signs do not automatically mean that you have breast cancer.
By performing monthly breast self-exams, you will be able to more easily identify any changes in your breast. Be sure to talk to your healthcare professional if you notice anything unusual.

Most often, these symptoms are not due to cancer, but any breast cancer symptom you notice should be investigated as soon as it is discovered. If you have any of these symptoms, you should tell your healthcare provider so that the problem can be diagnosed and treated. If I have no symptoms, should I assume I do not have cancer? Although there’s no need to worry, regular screenings are always important. Your doctor can check for breast cancer before you have any noticeable symptoms. During your office visit, your doctor will ask about your personal and family medical history and perform a physical examination. In addition, your Healthy Habits
Although you cannot prevent cancer, some habits that can help reduce your risk are:
A doctor may order one or more imaging tests, such as a mammogram.
