Diseases

One of the most talked about diseases is skin cancer. Cancer is a broad term that describes diseases caused by abnormal cells in the body dividing uncontrollably. Most cancers are identified by the organ or tissue in which the cancer originates. One common form of cancer is skin cancer. The Skin Cancer Foundation reports that one in five Americans will experience some type of skin cancer in their lifetime. The degradation of the ozone layer in the atmosphere and the resulting increase in exposure to UV radiation has contributed to its rise. Overexposure to UV radiation damages DNA, which can lead to the formation of cancerous lesions. Although melanin offers some protection against DNA damage from the sun, often it is not enough. The fact that cancers can also occur on areas of the body that are normally not exposed to UV radiation suggests that there are additional factors that can lead to cancerous lesions.

Q. All of the following statements are true of cancer except …

• a. The term "cancer" usually describes diseases that cause irregular cells to multiply uncontrollably

• b. The most common and fatal form of cancer is skin cancer

• c. Approximately 20% of Americans will experience a form of skin cancer

• d. Harm to our DNA can cause cancerous spots to form

B is correct because the modifier “most” is not used in the original statement about skin cancer; the passage states that skin cancer is “one common form of cancer”. The passage also does not mention anything about it being the most fatal form.
