Which of the following best describes cancer?
A group of diseases characterized by uncontrolled and abnormal cell proliferation, loss of regulation over growth, differentiation, and death, and the potential to invade other tissues (metastasis)
A single disease caused by bacteria
A viral infection that only affects the skin

What is meant by metastasis in the context of cancer?
The potential of cancer cells to invade other tissues
The process of normal cell division
The death of healthy cells
The differentiation of stem cells
Which of the following is NOT a characteristic of cancer?
Controlled cell growth and differentiation
Uncontrolled and abnormal cell proliferation
Loss of regulation over cell death
Potential to invade other tissues
Loss of regulation over growth, differentiation, and death is significant in the development of cancer because:
It allows cells to multiply uncontrollably and avoid normal processes that would limit their growth, leading to tumor formation and potential spread to other tissues.
It helps the immune system fight infections more effectively.
It causes cells to become more specialized and function better.
It prevents cells from dividing, stopping tissue growth.
Which of the following is a key feature of cancer cells that allows them to evade programmed cell death?
Angiogenesis
Metastasis
Avoid Apoptosis
Sustained Proliferation
What is the process called by which cancer cells promote blood vessel formation to support rapid growth?
Metastasis
Apoptosis
Angiogenesis
Proliferation
Cancer cells are able to grow and divide out of control primarily due to which of the following?
Increased blood supply
Genetic mutations such as oncogenes and tumor suppressor gene loss
Enhanced immune response
Reduced oxygen supply
Which feature of cancer cells enables them to spread to distant organs through blood or lymph?
Angiogenesis
Metastasis
Apoptosis
Proliferation
Sustained proliferation in cancer cells contributes to tumor growth by allowing cells to divide uncontrollably due to genetic mutations. Which of the following best explains this process?
Sustained proliferation allows cancer cells to divide uncontrollably due to genetic mutations, such as activation of oncogenes and loss of tumor suppressor genes, leading to tumor growth.
Sustained proliferation causes cancer cells to die quickly, preventing tumor growth.
Sustained proliferation increases blood vessel formation, which directly causes tumor growth.
Sustained proliferation makes cancer cells less likely to spread to other organs.
A researcher observes that a group of cells is able to survive much longer than normal cells and does not undergo programmed cell death. Which key feature of cancer cells is most likely being observed, and what is its significance in cancer development?
Angiogenesis; it helps the cells form new blood vessels.
Metastasis; it allows the cells to spread to other organs.
Avoid Apoptosis; it enables the cells to evade programmed cell death and live longer, contributing to cancer development.
Sustained Proliferation; it causes the cells to divide rapidly.

According to the Log-Kill Hypothesis, what does a chemotherapeutic drug kill in cancer treatment?
A constant proportion of cancer cells
A fixed number of cancer cells
All cancer cells at once
Only healthy cells
Why are multiple cycles of chemotherapy needed to cure cancer according to the Log-Kill Hypothesis?
Because each cycle only kills a constant proportion of cells, not all of them
Because cancer cells become immune after one cycle
Because the drug only works in the first cycle
Because the body needs time to recover between cycles
The Log-Kill Hypothesis justifies the use of repeated chemotherapy cycles in cancer treatment because:
Each cycle reduces the number of cancer cells by a constant proportion, not a fixed number, so multiple cycles are needed to eliminate all cancer cells.
Chemotherapy is only effective in the first cycle.
Cancer cells grow faster after each cycle.
The drug becomes more potent with each cycle.
Which type of tumors respond better to chemotherapy?
Tumors with high growth fraction (e.g., leukemias)
Tumors with low growth fraction (e.g., prostate cancer)

Tumors with high growth fraction are more responsive to chemotherapy compared to slow-growing tumors because:
Chemotherapy targets rapidly dividing cells, making it more effective against tumors with high growth fraction.
Chemotherapy only works on tumors with low growth fraction.
Slow-growing tumors have more blood supply, making chemotherapy more effective.
Chemotherapy is less effective against all types of tumors.

Why does the maximum tolerable dose (MTD) limit the effectiveness of chemotherapy?
Because higher doses cause unacceptable toxicity to normal cells
Because cancer cells become resistant at higher doses
Because chemotherapy is only effective at low doses
Because MTD increases the risk of infection
Chemotherapy can cause side effects in tissues other than cancer cells because:
It targets all fast-dividing cells, including normal ones, leading to toxicities that limit the maximum tolerable dose.
It only targets cancer cells, so side effects are rare and do not limit dosing.
It strengthens normal cells, allowing for higher doses to be used safely.
It is ineffective at all doses due to rapid drug clearance.

Tumors are made up of identical cells with the same genetic mutations.
Tumors are not uniform and contain different cell populations with varied genetic mutations within the same cancer.
Tumors only contain healthy cells.
Tumors are always easy to treat with a single drug.
Why does tumor heterogeneity make it difficult to treat cancer with a single drug?
Because all tumor cells respond the same way to treatment.
Because single drugs are too expensive.
Because different cell populations within the same tumor may respond differently to the drug.
Because tumors are always resistant to all drugs.
A researcher is developing a new cancer drug. Based on the concept of tumor heterogeneity, what should the researcher consider to improve the effectiveness of the treatment?
Use a single drug that targets only one type of cell mutation.
