A woman's breast is made up of lobules, which are glands that make milk; ducts, which connect lobules to nipples; fat and connective tissues; blood vessels; and lymph vessels. Most breast cancers begin in ducts. It may also begin in lobules then spread to other tissues.

When one feels a lump in breast, there is really no virtual worry because most lumps are benign which means that they are not cancerous. In fact, benign breast tumors are abnormal growths but do not really pose threats because they do not spread outside of breast. However, some benign lumps increase risk in having breast cancer.

Then there are lumps that are not really tumors at all which are often caused by fibrocystic changes -- cysts are fluid-filled sacs while fibrosis is formation of scar-like tissue. These changes can cause swelling of breasts resulting to being lumpy and sometimes a fluid discharge from nipples.

There are different types of breast cancer and knowing them will greatly help in assessing disease.

Carcinoma in situ is a term used for early stage of breast cancer where cancer cells are still confined to place where it started. In particular, cancer cells are confined in lobules or ducts, depending on where it started. The cancer cells have not gone into fatty tissues in breast nor spread to other organs of body.

Postpartum depression can occur in up to 16% of new moms, but this number may actually be higher due to amount of untreated depression. Don't confuse 'baby blues' with postpartum depression.
