Characteristics and Mechanisms of Cancer Quiz

Cancer is characterized by uncontrolled cell growth, leading to the formation of tumors.

Mutations leading to cancer are often caused by exposure to harmful chemicals.

Metastasis refers to the spread of cancer cells from the primary site to other parts of the body.

Melanoma is a type of cancer characterized by uncontrolled growth of pigment-producing cells in the skin.

Tobacco use is a significant risk factor for developing cancer, particularly lung cancer and other respiratory cancers.

Angiogenesis, the formation of new blood vessels, contributes to the spread of cancer cells and metastasis.

Tumor suppressor genes play a crucial role in inhibiting abnormal cell division and preventing cancer development.

Oncogenes play a role in promoting cell growth and can contribute to the development of cancer.

Antibiotic therapy is not a common treatment modality for cancer; it is typically used for bacterial infections.

Sudden weight gain is not a common symptom of cancer; other symptoms like unexplained weight loss are more indicative of the disease.

The PI3K/AKT/mTOR pathway is frequently dysregulated in cancer, contributing to uncontrolled cell growth.

A tumor is a mass of abnormal cells that can potentially invade nearby tissues and develop into cancer.

Stage IV is the advanced stage of cancer where metastasis is present, indicating the spread of cancer to distant organs.

Lymphoma is a type of cancer that originates from cells of the immune system, particularly lymphocytes.

A biopsy involves the removal of a sample of tissue for microscopic examination to diagnose or evaluate the extent of cancer.
