How is cancer prevented?
A scientist from the School of Medicine of Harvard says that 75% of cancer deaths in the United States can be prevented. The best ways to prevent cancer disease are:
Avoid tobacco: smoking cigarettes increases the risk of many types of cancer, being lung cancer the most common. So, avoid smoking and even exposure.
Consume healthy food: Reduce the consumption of saturated fat and red meat while increasing the consumption of fruits, vegetables and whole grains.
Practice sport regularly: Exercising contributes to lower risks of suffering from colon cancer and reduce woman’s risk of breast cancer. Even if you don’t lose weight, physical activity is beneficial.
Maintain an adequate weight: If you are overweight, it’s time to start consuming fewer calories and burn more through exercise. Having a healthy diet and exercising are the best ways to stay lean.
Drink less: consuming too much alcohol cannot only lead you to addiction but also increase the risk of cancer disease. Combining alcohol and tobacco can accelerate the appearance of certain types of cancer.
Avoid exposure to radiation and toxins: control the levels of residential radon and protect yourself from sunlight, both factors can produce lung cancer and skin cancer respectively. If you work in the chemical industry, always protect yourself from dangerous chemicals like benzene and aromatic amines.
What is the best diet for cancer prevention?
Probably the healthiest diet is the Mediterranean diet, which is rich in fruit, vegetables, seafood and healthy fats like olive oil and low in red meats and sugary desserts.
Changing eating habits is not an easy task, but it’s worth the effort. Start eating fruits and dried fruit as snacks instead of cookies or candies. Add more vegetables to your meals, especially whole grains. Broccoli, carrots, berries and citrus fruits contribute greatly to cancer prevention.
What is the primary prevention of cancer?
Primary prevention is about people choosing healthy behaviours to lower the risks of cancer disease. As stated above, educating people to choose a healthy lifestyle that includes more exercise, healthy diet and less tobacco and alcohol is the first step to prevent cancer.

Other ways of preventions are promoting the use of vaccines that protect people from dangerous infections like human papillomavirus (HPV) and supporting policies which make the environment we live safer, like smoke-free policies.
What are 5 causes of cancer?
The World Health Organization create a road map to reduce premature deaths from cancer and other non-communicable diseases which includes a list of risk factors.
Probably the more common of all is tobacco. Cigarettes content 7000 chemicals, 250 chemicals of them are known to be harmful and around 69 can cause cancer. Tobacco kills approximately 8 million people worldwide, from cancer and other diseases.
Another risk factor is obesity or overweight. Several types of cancer are linked to an excess in body mass, such as esophagus, colorectal and kidney cancer. Overweight was behind 4,3% of cancer cases in 2012, including 110,000 cases of breast cancer per year.
Alcohol consumption is related to cancer of the oral cavity, pharynx and liver. In 2016, approximately 400.000 deaths worldwide were attributed to alcohol use, mainly among men.
In the last years, pollution has become a major problem for many countries and one of the reasons is its relation to cancer disease, claimed prostate cancer Sydney. Estimations say that outdoor air pollution is responsible for around 4.2 million deaths worldwide, and 6% of them were lung cancer deaths.
Finally, another important risk factor is radiation. Both natural and artificial radiation can increase the risk of experiencing cancer disease. Ultraviolet radiation, specifically solar radiation, can cause major types of skin cancer like basal cell carcinoma (BCC) and melanoma.
What foods cause cancer?
Researches point out that red and processed meats are the most worrying in terms of cancer risk. Red meats include pork, beef and lamb. Processed meats include bacon, meat jerky, hot dogs, salami, ham and any other cured meat product. Eating any amount of processed meat and around 18 ounces of fresh meat per week are strongly related with a high risk of cancer.
