What are the two cause of cancer?

What are the two cause of cancer?

A number of forces can cause gene mutations, such as smoking, radiation, viruses, cancer-causing chemicals (carcinogens), obesity, hormones, chronic inflammation and a lack of exercise.

What are some factors that can cause cells to become cancerous?

More often genetic changes that cause healthy cells to turn cancerous are triggered by external factors such as exposure to chemicals, radiation or lifestyle choice, as opposed to genetic defects that have been present since birth. All cells within the body have a purpose.

What are two environmental factors that can cause cancer?

Environmental factors that cause cancer

• Lifestyle factors (nutrition, tobacco use, physical activity)
• Natural occurring exposures (ultraviolet light, radon gas, infectious agents)
• Medical treatments (radiation and medicine)
• Workplace and household exposures.
• Pollution.

What is the leading cause of cancer?

While smoking is still by far the biggest cause of cancer and cancer deaths, obesity, poor diet and drinking too much alcohol cause an increasing number of cancer cases and deaths.

What is cancer and how does it form?

Cancer is the uncontrolled growth of abnormal cells in the body. Cancer develops when the body’s normal control mechanism stops working. Old cells do not die and instead grow out of control, forming new, abnormal cells. These extra cells may form a mass of tissue, called a tumor.

What type of cancers are caused by environmental factors?

Table 1:

Carcinogens	Cancer Sites	Occupational Sources
Arsenic	Lungs, Skin	Electricians, Smelters, Medications.
Asbestos	Mesothelioma, Lungs	Roof and floor tiles
Benzene	Blood and lymph nodes	Petroleum, painting, detergent, rubber
Beryllium	Lungs	Missile fuel, Nuclear reactor

What are the top 3 causes of cancer?

Common Causes of Cancer

• Smoking and Tobacco.
• Diet and Physical Activity.
• Sun and Other Types of Radiation.
• Viruses and Other Infections.

What are five causes of cancer?

The most common risk factors for cancer include aging, tobacco, sun exposure, radiation exposure, chemicals, and other substances, some viruses and bacteria, certain hormones, family history of cancer, alcohol, poor diet, lack of physical activity, or being overweight.

What factors are associated with causing cancer?

Cancer is caused by both external factors (tobacco, chemicals, radiation and infectious organisms) and internal factors (inherited mutations, hormones, immune conditions, and mutations that occurs from metabolism). We will go into the external factors a bit more detail here.

What is the greatest risk factor for cancer?

It has long been widely accepted that the single greatest risk factor for developing cancer is aging, e.g., cancer is considered a disease of aging. Aging is not a disease per se, but it is often closely associated with diseases, including cancer.

Are there certain foods that cause cancer?

Some specific foods are linked to specific cancers. Studies have linked eating red or processed meat to an increased risk of breast cancer, colon cancer, prostate cancer, and pancreatic cancer, which may be partially explained by the presence of carcinogens in foods cooked at high temperatures.

What cancers are caused by environmental factors?

Some environmental factors are linked to specific types of cancer. For example, we know asbestos causes lung cancer, Benzedrine (a chemical in dyes) causes bladder cancer, and tobacco causes lung and other cancers.
