Which grade of tumor is also known as a well differentiated tumor?

High-grade (grade 3) cancer cells appear distinctly abnormal under the microscope. Low-grade tumors are often referred to as well-differentiated, while high-grade tumors are called poorly differentiated or undifferentiated. Typically, high-grade tumors are more likely to grow and spread faster than low-grade tumors.

What health problems do benign tumors cause?

Noncancerous moles or colon polyps, for example, can turn into cancer at a later time. Some types of internal benign tumors may cause other problems. Uterine fibroids can cause pelvic pain and abnormal bleeding, and some internal tumors may restrict a blood vessel or cause pain by pressing on a nerve.
