It is important to be educated about breast cancer because there are many different lumps that may or may not be cancerous or lead to cancer. Lumps that occur in the breast are common and may not be cancerous and should be checked to make certain. These lumps occur in women about one or two weeks before their period. Fibrocystic disease occurs with hormonal changes. Most ordinary benign lumps are harmless and do not turn cancerous or increase the chances of getting cancer with the increase in age.
Atipical hyperplasia is the term used for the change in a benign lump.
This may increase the chances of developing cancerous cells and also signals instability of the breasts. Carcinoma in situ is when the cells stay in the duct or lobules and are not invasive. Invasive is the term used when the cells spread out of the duct or out of the lobule. The most important fact to notice about benign lumps are the changes that occur. It is crucial that breast self-exams are done often to notice the changes in your breasts.
