What is a spindle cell tumor in the stomach?
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.
Tumor cells replicate continuously due to genetic mutations that disrupt normal cell cycle regulation. These mutations can activate oncogenes, which promote cell proliferation, and inhibit tumor suppressor genes, which normally prevent excessive cell growth. This uncontrolled replication is a hallmark of cancer.
Yes, tumor viruses can contain genes found in normal cells. Some tumor viruses are able to integrate their genetic material into the host cell's genome, which can disrupt normal cellular functions and lead to uncontrolled cell division and tumor formation.
A tumor arising from an astral cell is called an astrocytoma. Astrocytomas are a type of brain tumor that originates from astrocytes, which are a type of star-shaped glial cell in the brain and spinal cord.
Oncogenes regulate cell division, so if it is placed near an overly active gene, it may itself become overly active, thus causing cancer. Tumor suppressors suppress tumors and will only cause cancer if it stops its activity, contrary to oncogenes.

Mitosis is not regulated in Tumor Cells -> Apexvs
a mutation occurs in a cell then a tumor forms
A bad smell associated with a mast cell tumor may be due to infection or necrosis (tissue death) within the tumor.
It can be genetic, as germ cell tumor.
A giant cell tumor is a benign but locally aggressive tumor that usually occurs in the bones, most commonly in the long bones of the arms and legs. It is characterized by the presence of many multinucleated giant cells within the tumor tissue. Surgical treatment is often required to remove the tumor and prevent recurrence.
A tumor just refers to an abnormal growth of cells that form a swollen growth. A tumor is not necessarily cancer. It may be benign or malignant.
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.

NEUROCRINE CARCINOMA is an old and somewhat ambiguous entity of malignant tumor. In general, NC is a tumor that demonstrates neurocrine differention. That can be a usual carcinoma with prominent neurocrine differention, a large cell neurocrine carcinoma, small cell carcinoma or an atypical carcinoid tumor(in the lung). NEUROCRINE CARCINOMA is an old and somewhat ambiguous entity of malignant tumor. In general, NC is a tumor that demonstrates neurocrine differention. That can be a usual carcinoma with prominent neurocrine differention, a large cell neurocrine carcinoma, small cell carcinoma or an atypical carcinoid tumor(in the lung).
In general, the less specialized the cell type, the more malignant the tumor.
When the cell cycle become uncontrolled, a tumor can form.
