TYPES OF BREAST CANCER
Most tumors occur in the breast are benign, not cancerous, and are due to fibrocystic formations. The cyst is a fluid-filled sac fibrosis and abnormal development of connective tissue. Fibrosis does not increase the risk of developing a tumor and does not require special treatment. The cysts, if large, can be painful.
Removing the fluid with a needle tends to remove the pain. The presence of one or more cysts does not favor the appearance of malignant tumors. Benign tumors are mostly related to genetic factors. The symptoms are pain and swelling occur but not spread to the rest of the body are not dangerous. In malignant tumors, there are several types depending on the location of the breast where abnormal growth occurs the cells and by stage. Tumors may be localized or have spread through the blood vessels or via the lymphatic vessels, and have led to metastasize, cancer in an organ distant to the original.
In all cases of breast cancer only 7-10% of them presented metastasis onset. The breast cancers are classified as ductal carcinoma in situ in the cells of the walls of the ducts. It is a very localized cancer that has not spread to other areas has not metastasized. That is why this disease ‘premalignant’ can be removed easily. The cure rate close to 100%. This type of tumor can be detected through a mammogram. ductal carcinoma (or invasive) is the one that begins in the milk duct but manages to get through and enters the fatty tissue of the breast and then can spread to other parts of the body.
It is the most common breast carcinoma, occurs in 80% of cases. lobular carcinoma in situ originates in the mammary glands (or lobes) and, while not a true cancer, increases the risk that women can develop a cátumor in the future. It is usually given before menopause. Once it is detected, it is important that women have a mammogram every year control and several clinical tests to monitor the possible development of cancer. lobular carcinoma infiltrating (or invasive) starts in the mammary glands but it can spread and destroy other body tissues. Between 10% and 15% of breast cancers are this type.
This carcinoma is more difficult to detect through mammography. Inflammatory carcinoma is a rare cancer, accounting for only 1% of all breast cancers. It is aggressive and fast growing. Blush breast skin and increase its temperature. The appearance of the skin becomes thick and hollow, like an orange, and wrinkles and bumps may appear. These symptoms are due to blockages that cause cancer cells on the lymph vessels.
