Breast cancer is a type of cancer that originates from tissues in the breasts commonly from within the inner lining of milk ducts or alternatively lobules which supply milk to the ducts. Breast cancer can occur in both humans and other mammals but .The majority cases in humans occur in women, however breast cancer also occurs in men but in very rare instances. Those few cases of breast cancer in men occur to men in the ages between 60 and 70.from statistics white women are seen to be at a higher risk of the development of malignant breast cancer as compared to Hispanics or Asians. Breast cancer comes second when it comes to cause of deaths due to cancer in women aged between 45-50.there is an increase in the number of women who are diagnosed with cancer each year. If cancer is detected early enough than the chances of survival rate is increased. Annual breast cancer screening and preventive steps at early stages can be of great assistance when it comes to the monitoring of early stages. Cancer can be broadly categorized into two, invasive and non-invasive. Under these two broad categories there are three different types of breast cancer which are ductal carcinoma in situ which is the most common type of noninvasive and it has not spread and therefore has a high cure rate. The other one is Invasive ductal carcinoma, starts in the breast duct and proceeds to the surrounding tissue. This is the most common breast cancer. The last common type of breast cancer is Invasive lobular carcinoma starts begin in breast glands that produce milk.

One has a certain type of breast lamps then they have a high chance of developing breast cancer. These can be non-cancerous breast lumps which include ductal hyperplasia; dense breast tissue is another risk factor whereby women who have dense breast tissue are more likely to develop breast cancer.
