Substances that causes cancer.
Carcinogens
Abnormal mass of tissue arising from an abnormal proliferation of cells.
Neoplasm
To spread from one part of the body to another part not directly connected to the first part. Cancerous tumors do this and form new tumors in distant parts of the body.
Metastasis
A neoplasm. An abnormal growth of cells. They form from the new growth of tissue in which cell division is uncontrolled and progressive.
Tumor
A broad goup of diseases involving unregulated cell growth. (web)
Cancer
A gene that has the potential to cause cancer. (web)
Oncogenes
The process of programmed cell death. (web)
Apoptosis
The changes in shape, nuclei, or organization of adult cells. It is typical of precancerous cells.
Dysplasia
A normal gene that can become an oncogene due to mutations or increased expression.
Proto-Oncogenese
Early form of cancer that is defined by the absence of invasion of tumor cells into the surrounding tissue. (web)
Carcinoma in situ
Any additional sites where the cancer has spread. (web)
Secondary Tumor
The creation of cancer, normal cells are transferred into cancer cells. (web)
Carcinogenesis
The likely course of a disease or aliment. (web)
Prognosis
Drugs which inhibits or prevents the function of cells. (web)
Cytotoxic Drugs
A cancerous tumor. An abnormal mass of tissue with cells that can invade surrounding tissue and spread to multiple locations throughout the body.
Malignant Tumor
