Answer 1

Answer 1: Lung ( Option B )

Lung cancer are the most common cause of death.

Main cause of lung cancer is the use of tobacco products.

Answer 2: True

Cancer death caused by certain lifestyle habits such as drinking alcohol, smoking, not maintaining body weight, too much exposure to UV radiation are easily avoidable.

Cancer is caused by certain changes to genes that control the way our cells function, especially how they grow and divide.

Cancer-causing genetic changes can also be acquired during one’s lifetime, due to the exposure to carcinogenic substances that damage DNA.

Damaged DNA can cause cells to evade normal growth controls and become cancer.

Answer 5: True

Obese people have increased chance of getting cancer due to the fact that extra fat cells makes extra hormones and growth factors. These growth factors and hormones leads to increased division of cells which can also increase the chances of abnormal growth of the cell. These abnormal growth of cell causes tumor formation.

Excess fat doesn’t have much room for oxygen and low-oxygen environment triggers inflammation.

Long-term inflammation caused by excess fat can damage your body and increase risk for cancer.

High estrogen levels lead to increased cell production, which could result in tumor growth.
