Question 1

Research has shown a consistent and strong link between taking beta-carotene supplements and a reduced risk of developing cancer.

Accepted Answer

While beta-carotene is a powerful antioxidant that has been linked to many health benefits, including reducing the risk of certain types of cancer, studies have not consistently shown a strong link between taking beta-carotene supplements and a reduced risk of cancer. In fact, some studies have even suggested that high doses of beta-carotene supplements may increase the risk of certain types of cancer, such as lung cancer in smokers. Therefore, it is important to get beta-carotene from natural food sources rather than relying on supplements.

Question 2

At what stage in the development of cancer do the cancerous cells grow out of control and invade surrounding tissues?&#10;A)initiation&#10;B)promotion&#10;C)progression&#10;D)termination

Accepted Answer

The stage in which cancerous cells grow out of control and invade surrounding tissues is called progression. Initiation is the first stage where a genetic mutation occurs and promotion is when these mutated cells begin to divide and form a tumor. Termination is not a stage in cancer development.

Question 3

Which of the following terms is synonymous with the word malignant?&#10;A)tumor&#10;B)benign&#10;C)undifferentiated&#10;D)cancerous

Accepted Answer

The term malignant is used to describe cancerous growths or tumors, which means they are capable of invading nearby tissues and spreading to other parts of the body. The other choices are not synonymous with malignant - benign tumors are non-cancerous, undifferentiated tumors are those that have not yet developed specific features of the tissue they originate from, and tumor is a general term for any abnormal growth of tissue.

Question 4

Approximately half of all cancers are strongly hereditary.

Accepted Answer

Only a small percentage of cancers (5-10%) are directly linked to inherited genetic mutations. The majority of cancers develop from a combination of genetic and environmental factors.

Question 5

Cooking meat at high temperatures can result in the formation of&#10;A)nitrates.&#10;B)phytoestrogens.&#10;C)heterocyclic amines.&#10;D)omega-3 fatty acids.

Accepted Answer

Cooking meat at high temperatures can lead to the formation of heterocyclic amines (HCAs), which are carcinogenic compounds. Nitrates are typically found in cured meats and are not directly related to high temperature cooking. Phytoestrogens are compounds found in plants and are not commonly associated with meat. Omega-3 fatty acids are found in fatty fish and are not directly related to meat cooking methods.

Question 6

Once the DNA of the cell is mutated and the altered cells begin to grow, the development of cancer is inevitable.

Accepted Answer

Mutations can occur in cells, but not all mutations lead to cancer. It also depends on the type and location of the mutation, as well as other genetic and environmental factors. Early detection and treatment can also prevent the development of cancer.

Question 7

Skin cancer is the most common form of cancer in the United States.

Accepted Answer

According to the American Academy of Dermatology, skin cancer is the most common form of cancer in the United States, with over 9,500 people diagnosed every day.

Question 8

How many cancer deaths are estimated by researchers to be related to overweight/obesity, poor nutrition, and inadequate physical activity?&#10;A)one-quarter&#10;B)one-third&#10;C)one-half&#10;D)three-quarters

Accepted Answer

Researchers estimate that one-third of cancer deaths are related to overweight/obesity, poor nutrition, and inadequate physical activity.

Question 9

Eating whole foods that are high in antioxidants, such as fruits, vegetables, and whole grains, is consistently shown to be associated with a decreased risk of cancer.

Accepted Answer

Numerous studies have shown that consuming a diet rich in whole foods that are high in antioxidants, such as fruits, vegetables, and whole grains, is associated with a decreased risk of cancer. Antioxidants can protect cells from damage caused by free radicals, which are unstable molecules that can contribute to the development of cancer. Additionally, many fruits and vegetables contain other nutrients and compounds that have been shown to have cancer-fighting properties.

Question 10

Which of the following is NOT a sign or symptom of cancer?&#10;A)unexplained weight gain&#10;B)fever&#10;C)unexplained weight loss&#10;D)nagging cough or hoarseness

Accepted Answer

Unexplained weight gain is not typically a sign or symptom of cancer. In fact, many cancers are associated with unexplained weight loss. Fever and nagging cough or hoarseness can be symptoms of certain types of cancer, while unexplained weight loss is a common symptom across different types of cancer.

Question 11

The majority of people who develop cancer will die from the disease.

Question 12

The MOST common form of cancer in the United States is cancer of the&#10;A)lung.&#10;B)skin.&#10;C)colon.&#10;D)stomach.

Accepted Answer
