Which of the following characteristics distinguishes cancer cells from normal cells in terms of their growth and development?
Which of the following characteristics distinguishes cancer cells from normal cells in terms of their growth and development?
- Cancer cells typically mature at an accelerated rate compared to normal cells.
- Cancer cells always maintain the same rate of division.
- Cancer cells have a longer programmed lifespan.
- Cancer cells divide more rapidly and may fail to reach full maturity, unlike normal cells with programmed lifespans. (correct)
A researcher is investigating a new chemical compound. What evidence would classify this compound as a Group 1 carcinogen?
A researcher is investigating a new chemical compound. What evidence would classify this compound as a Group 1 carcinogen?
- The compound only increases cancer risk in certain kinds of plants.
- The compound has been shown to increase cancer risk in human populations through epidemiological studies. (correct)
- The compound demonstrates the ability to boost the immune system in vitro.
- The compound is often found in healthy foods.
Which statement accurately differentiates between benign and malignant tumors?
Which statement accurately differentiates between benign and malignant tumors?
- Benign tumors always metastasize, while malignant tumors remain localized.
- Benign tumors are typically not life-threatening as they do not spread, whereas malignant tumors are cancerous and can spread to other parts of the body. (correct)
- Benign and malignant tumors are equally dangerous.
- Benign tumors contain healthy cells, while malignant tumors contain abnormal cells.

Study Notes
- Cancer cells are considered "abnormal" if they divide faster than normal cells, fail to reach maturity, or ignore programmed life span limits.
- A carcinogen is any substance or agent known to increase the risk of cancer in humans.
- Examples of Group 1 carcinogens: tobacco and UV light.
Benign Tumors
- Composed of abnormal cells, but generally pose no threat because they do not spread.
Malignant Tumors
- Cancerous and contain abnormal cells; a person with a malignant tumor is considered to have cancer.
Metastasis
- Cancer spreads to other sites in the body. This is significant because it indicates the cancer has the ability to invade other tissues and organs, making it more dangerous and harder to treat.
Cancer Staging
-
Stage 1 cancer is usually smaller and localized, whereas Stage 4 cancer typically indicates that the cancer has spread more widely throughout the body.
-
Melanoma is a deadly skin cancer that develops in pigment-producing cells (melanocytes).
-
Skin cancer is the most common type of cancer.
-
Lung cancer is the deadliest type of cancer.
-
Leukemia is the most common cancer in children, primarily affecting white blood cells.
-
A dermatologist would likely perform a skin biopsy on a suspicious mole to determine if it is cancerous.
-
Surgery is usually the first cancer treatment performed.
-
Chemotherapy is effective at treating widespread cancer, but side effects include hair loss and nausea.
-
Immunotherapy aims to enable a person's immune system to fight cancer cells.
