Breast cancer is a disease in which cells in the breast grow out of control. There are different kinds of breast cancer. The kind of breast cancer depends on which cells in the breast turn into cancer. Breast cancer can begin in different parts of the breast. A breast is made up of three main parts: lobules, ducts, and connective tissue. The lobules are the glands that produce milk. The ducts are tubes that carry milk to the nipple.
The connective tissue (which consists of fibrous and fatty tissue) surrounds and holds everything together.
Most breast cancers begin in the ducts or lobules. Breast cancer can spread outside the breast through blood vessels and lymph vessels. When breast cancer spreads to other parts of the body, it is said to have metastasized.
Kinds of Breast Cancer
The most common kinds of breast cancer are—Invasive ductal carcinoma. The cancer cells begin in the ducts and then grow outside the ducts into other parts of the breast tissue. Invasive cancer cells can also spread, or metastasize, to other parts of the body.
Invasive lobular carcinoma. Cancer cells begin in the lobules and then spread from the lobules to the breast tissues that are close by. These invasive cancer cells can also spread to other parts of the body.
Carotenoids are very important part of our diet, Looking for another reason to add carrots to your lunch or collard greens to dinner? Well, these are great sources of beta-carotene and alpha-carotene, types of carotenoids found in fruits and vegetables. And there are new studies that suggests that women with higher blood concentrations of these carotenoids are at decreased risk of the type of breast cancer called estrogen receptor (ER) negative.
ER negative breast cancer don’t have receptors for the hormone estrogen. These tumors are less common and often more difficult to treat than the more common ER-positive tumors that typically respond to estrogen.
Carotenoids are a large group of phytochemicals found in fruits and vegetables. You can usually recognize them by the orange, red, and yellow colors they give to foods. Many green leafy vegetables are also great sources.
These results may be another reason to consume more foods with beta carotene and alpha carotene. Supplements are not associated with the same decreased risk. And β-carotene in high-dose supplements, especially in smokers, seems to increase lung cancer risk and mortality.
