What is a Grade 4 Tumour?

What is a low grade tumor?
A term used to describe cells and tissue that look almost normal under a microscope. Low-grade cancer cells look more like normal cells and tend to grow and spread more slowly than high-grade cancer cells. Cancer grade may be used to help plan treatment and determine prognosis.
What does high grade tumor mean?
High grade or grade III tumor cells are poorly differentiated. This means that the tumor cells don’t look like normal cells. They’re disorganized under the microscope and tend to grow and spread faster than grade I tumors.
How are cancer tumors measured?

Does tumor size determine cancer stage?
Tumor Size and Staging Tumor size is strongly related to prognosis (chances for survival). In general, the smaller the tumor, the better the prognosis tends to be . Tumor size is part of breast cancer staging. In the TNM staging system, a “T” followed by a number shows the size of the tumor.
What determines tumor stage?
The cancer’s stage tells you where a cancer is located and its size, how far it has grown into nearby tissues, and if it has spread to nearby lymph nodes or other parts of the body. Before starting any cancer treatment, doctors may use physical exams, imaging scans, and other tests to determine a cancer’s stage.
