A new lump in the breast or armpit Thickening or swelling of part of the breast. Irritation or dimple formation on the skin of the breasts Redness or scaly skin in the nipple area or on the breast. Doctors know that breast cancer occurs when certain breast cells begin to grow abnormally. These cells divide more quickly than healthy cells and continue to build up, forming a lump or mass.
The cells can spread (metastasize) through the breast to the lymph nodes or to other parts of the body. In short, the stage describes how widespread or advanced the cancer is in breast tissue and possibly in other parts of the body. Approximately 5% to 10% of breast cancers are due to a genetic abnormality inherited from the mother or father. Hormone therapy has its own side effects, but your doctor can guide you on the best options for your specific type of cancer.
This condition is usually found when a doctor performs a breast biopsy for another reason, such as to investigate an unrelated breast lump. Invasive breast cancer refers to breast cancer that spreads from the original site to other areas of the breast, lymph nodes, or any other part of the body. Men and women who have inherited these genetic mutations have a higher risk of developing breast, prostate and other types of cancer. Breast cancer is a malignant tumor that develops from the uncontrolled growth of abnormal breast cells.
Researchers have identified hormonal, environmental and lifestyle factors that may increase the risk of breast cancer. Because the main symptom of breast cancer is an abnormal lump in the breast and because non-invasive breast cancer is usually accompanied by a tumor so small that it can only be detected by a mammogram, non-invasive breast cancer is unlikely to cause noticeable physical symptoms. Like any cancer, breast cancer is the result of DNA mutations that tell cells to grow out of control. At this point, the tumor cells have spread to the surrounding normal breast tissue, but are still contained in a small area.
Identifying breast cancer at its earliest stages is not easy because the signs and symptoms of breast cancer are different from person to person. Breast cancer can also start in glandular tissue called lobules (invasive lobular carcinoma) or in other breast cells or tissues. Whether you're a man or a woman, it's important to familiarize yourself with your breasts so you can recognize the changes and seek timely treatment.
