Breast cancer doesn't occur in one single part of the breast, it can begin in different areas of the breast including:
• the ducts
• the lobules
• the tissue in between
There are many types of breast cancer, but two are more common in most women. They generally are named after the parts in the breast in which they start occurring. The first is ductal carcinoma and the second is lobular carcinoma. Those two are the most common types, and they appear in the breast’s milk ducts or the milk-producing glands.
Invasive breast cancers are ones which spread outside the membranes which line the lobule, or the ducts, and start to invade the surrounding areas. They travel to other parts in the body which are more commonly known as lymph nodes. Invasive ductal carcinoma consists of nearly 70% of breast cancers. The lining of the milk ducts eventually get thin and break; the cancer spreads through the wall and starts to apply itself to the breast tissue.
The cells may keep near the site of origin, but they still spread through out the body by using a woman’s blood stream. Invasive lobular carcinoma is less common but it invades in a similar way as it starts in the milk producing lobules then starts to break into the surrounding tissue, but they can also have the same type of spreading on different parts of a woman’s body. This type of cancer does not necessarily provide lumps, but thickens an area in general. The most aggressive types of breast cancer is inflammatory as it starts form sheets and nests instead of lumps underneath the soft tissues of the breast. It can easily be treated with chemotherapy and with some surgery later on. If caught early it is manageable and the survival rates are increasing.
The least common type of cancer is the cancer of the nipple, which is called Paget’s disease. It starts to look like a skin rash or rough skin around the nipple, which some people may consider as eczema, but those are just the minor signs of cancer being under the surface of the skin. The best way to treat this type of cancer is mastectomy, since it is around the nipple and milk ducts.

Age and gender are the most common risks associated with the breast cancer. Breast cancer is reported to be developed by females more than males. However women at the younger age are not seen to have breast cancer. The probability of breast cancer increases as the women cross the age limit of 30 years. However, there are situations where women at an early stage can have breast cancer.
Personal history of breast or any other type of cancer increases the chances if breast cancer. Women who have been getting hormonal treatment for birth control or other hormone or other hormone replacement treatments are most likely to have breast cancer.

Breast cancer can also be inherited, for that matter first degree relatives take huge importance. For instance, if a woman has her mother or sister affected by breast cancer, she is most likely to have breast cancer. Second degree relatives (grandfathers and aunties) can also provide the risk of breast cancer.
Lifestyle
Smoking and alcohol acts as catalyst for breast cancer. Women who are smoker or consume alcohol as well have chances to develop breast cancer. Also women having no children or having their first child after 30 years of her age are vulnerable to the risk of breast cancer. With the same time women using birth control with higher level of estrogens can easily develop breast cancer, if they use oral contraceptive for a longer period of time.
Obesity resulted due to the consumption of fast increases the risk of breast cancer. Physical inactivity tends to increase the risk of breast cancer.
Environmental factors
Women who are exposed to chemicals e-g working on chemical factories and farm houses have greater tendency to develop breast cancer. Also environment of certain countries support the breast cancer to grow. For instance, Asian women are less likely to have breast cancer than women in United States.
