Most breast cancers begin in the cells that line the ducts ductal cancers. Some begin in the cells that line the lobules lobular cancerswhile a small number start in other tissues.
The lymph lymphatic system of the breast The lymph system is important to understand because it is one way breast cancers can spread. This system has several parts.

If the papilloma dcis cells have spread to lymph nodes, there is a higher chance that the cells could have also gotten into the bloodstream and spread metastasized to other papilloma dcis in the body.
The more lymph nodes that have breast cancer, the more likely it is papilloma dcis the cancer may be found in other organs as well. Because of this, finding cancer in one or more lymph nodes often affects the treatment plan.
Still, not all women with cancer cells in their lymph nodes develop metastases, and papilloma dcis women can have no papilloma dcis cells in their lymph nodes and later develop metastases. Benign breast lumps Most breast lumps are not cancerous benign. Still, some may need to be sampled and viewed under a microscope to prove they are not cancer.
