Breast cancer starts developing from the milk ducts that can spread in other body parts. Females are the primary ones that are affected with breast cancer although there are cases seen where men are affected too. This is the most common cancer in women.
Women from developed countries have a higher incidence than their counterparts in the developing nations of the world. Food and lifestyle habits are two contributory factors for this type of cancer.
There are two types of breast cancer:
- Invasive breast cancer – Invasive breast cancer occurs when the cancer cell leaks from its original duct and invades a near tissue. Abnormal cells with this cancer type can metastasize in the lymph nodes and other organs like lungs and the liver. The cancer cell can also pass in the bloodstream and the lymphatic system.
- Non- invasive breast cancer Non- invasive breast cancer remains on the inside of its original lobule or duct. This type of cell is also called pre- cancerous because they can develop to be invasive breast cancer even if it is still in its place and intact.
The very first symptom a woman can detect breast cancer is a lump in a part of the breast, however majority of these lumps are not malignant. All women should visit their ob-gynecologist for check- ups or assess it by themselves through self breast examination.
Other symptoms include:
- Pain located near or in the armpits
- Redness of the breasts’ skin
- Nipple rashes
- Thick breast tissues
- Changes of the breast shape and size
- Lumps in one of the armpits
- Flaking, peeling, or flaking of the skin in the nipple or the breast and
- Discharge in the nipple that can sometimes contain blood.
