What is considered a large fibroid?
Uterine Fibroids Overview
- Uterine fibroids are lumps or tumors that develop within uterine walls.

- Having fibroids does not increase the risk of developing leiomyosarcoma.

Why is tumor size important in breast cancer?
Tumor size is an important factor in breast cancer staging, and it can affect a person’s treatment options and outlook. Tumors are likely to be smaller when doctors detect them early, which can make them easier to treat. However, the size of the tumor is only one of the factors that doctors consider when staging a person’s breast cancer.

How many nodules are there in the same lung?
There are 2 or more separate tumor nodules in the same lobe of a lung. The cancer has also spread to lymph nodes within the lung and/or around the area where the bronchus enters the lung (hilar lymph nodes). These lymph nodes are on the same side as the cancer (N1).
What is the stage of lung cancer?
After someone is diagnosed with a lung carcinoid tumor, doctors will try to figure out if it has spread, and if so, how far. This process is called staging. The stage of a cancer describes how much cancer is in the body. It helps determine how serious the cancer is and how best to treat it.
