Description

Breast cancer is one of the leading causes of cancer-related deaths among American women today. In fact, it is THE leading cause of cancer-related deaths among women between the ages of 15 and 54. It is estimated that 60% or more of women's cancers are related to nutritional factors. Other estimates are that 50 to 95 % of all cancers are caused by the environment and diet.

There are several different types of breast cancer. In situ carcinoma is a type of cancer that is contained within the breast duct and does not invade adjacent, healthy breast tissue. More than 15% of all breast cancers diagnosed in the US are of this type. This number increases, however, in younger age groups.

Ductal carcinoma in situ (DCIS) accounts for 92% of diagnosed breast cancers in women between the ages of 30 and 39. This number drops to 43% of diagnosed breast cancers in women aged 40 to 49 years. This type of cancer forms a palpable lump and occurs in both pre- and post-menopausal women. It is usually localized, and because of this, can be completely removed surgically. If not treated, this type of cancer is likely to develop into an invasive type.

Lobular carcinoma in situ (LCIS), also known as lobular neoplasia, occurs most often in post-menopausal women. This type is usually not palpable. Between 25 and 35% of women with this type of cancer develop invasive cancer, sometimes after a latency period of up to 40 years.

Invasive ductal and lobular tumours account for almost 90% of all histologic types of invasive cancer.

Symptoms and Signs:

If you notice a lump or thickening in your breast tissue, have it checked out as soon as you can. Most of the time it is just fibrocytic changes that occur in your breasts and are of no real concern. Other symptoms include a change in the skin of the breast, such as dimpling or puckering, retraction of the nipple, or discharge from the nipple. There may also be redness or swelling, and your lymph nodes located in the armpits may be enlarged. Chronic fatigue often occurs with rapidly progressing cancers of any type.
