Astrocytomas originate in a particular kind of glial cells, star-shaped brain cells in the cerebrum called astrocytes.
What is a spindle cell tumor in the stomach?
An aster is formed at each pole of the spindle in animal mitosis. hence mitosis in animal cell is amphi astral.
A carcinoma is a malignant tumor that occurs in epithelial tissue.
The region of the viral genome (DNA in DNA tumor-viruses or RNA in RNA-tumor viruses) that can cause a tumor is called an oncogene. This foreign gene can be carried into a cell by the virus and cause the host cell to take on new properties such as immortalization and anchorage-independent growth.
A mass of new cells that forms from uncontrolled cell growth is refered to as a neoplasm. This can indicate a cancer or tumour, where cell growth is unchecked and defective.

The regulatory proteins that serve to prevent a cell from entering the S phase are called tumor suppressors. Tumor suppressors protect the cell that has DNA damage and stop it from moving to the next phase.
Uncontrolled cell growth is usually called a tumor. When there is a condition that causes uncontrolled cell growth of abnormal cells, it is called cancer.

If cell division were not controlled, there would be unrestricted over growth of cells to form a shapeless mass of cells called a tumor. Uncontrolled cell growth is called cancer
The two types of cell cycle genes that cause cancer cells to divide uncontrollably if mutated are called tumor suppressor genes and antioncogene
Astral rays does occur in animal cells not in plant cell
