What is Cancer?

Cancer has become one of the main diseases that afflict the population worldwide, accounting for approximately 10 million deaths each year 1.
Cancer is the uncontrolled growth and spread of cells. It can affect almost any part of the body. Cancer cell growths often invade surrounding tissue and can metastasize to another part of the body. Many types of cancer can be prevented by avoiding exposure to common risk factors, such as tobacco smoke. In addition, a significant proportion of cancers can be cured , by surgery, radiation therapy or chemotherapy, especially if they are detected early.

How to prevent it?

Between 30 and 50%2 of all cancer cases are preventable. Prevention is the most cost-effective long-term strategy for cancer control. ULSA TECH, being aware of this disease, has the obligation to promote a culture of prevention and increase knowledge of how to reduce exposure to cancer risk factors3.


Tobacco use is the largest avoidable risk factor for cancer mortality, killing approximately 6 million people each year. Tobacco smoke has more than 7,000 chemicals, of which at least 250 are known to be harmful and more than 50 are known to cause cancer.

Smoking tobacco causes various types of cancer. Secondhand or secondhand smoke has been shown to cause lung cancer in non-smoking adults.More than 80% of the 1.3 billion tobacco users in the world live in low- and middle-income countries4.

Physical inactivity, diet, obesity and overweight.

There is a relationship between being overweight and obesity with many types of cancer. Diets rich in fruits and vegetables can have an independent protective effect against many types of cancer. Regular physical activity and maintaining a healthy body weight, along with a healthy diet, greatly reduce the risk of this condition. These eating habits also reduce the risk of other non-communicable diseases.

Occupational carcinogens

More than 40 agents, mixtures, and exposure circumstances in the workplace are carcinogenic to humans and are classified as occupational carcinogens. Occupational carcinogens are causally related to lung cancer, mesothelioma, and bladder cancer. For example, mesothelioma (cancer of the outer lining of the lung or chest cavity) is largely due to work-related exposure to asbestos.

Environmental pollution

Pollution of air, water and soil with carcinogenic chemicals contributes to the increase of cancer in different degrees, depending on the geographic configuration. Outdoor air pollution has been estimated to contribute to 3.2 million premature deaths worldwide in 2012. In addition, more than 4 million people die prematurely from diseases attributable to household air pollution from cooking with solid fuels5. Exposure to carcinogens also occurs through food contamination, such as aflatoxins or dioxins.
