9 Cancer Prevention Tips to Reduce Risk of Cancer

The good news is that you can protect yourself from cancer by following a healthy lifestyle and avoiding some chemical substances (Carcinogens) that cause cancer. according to WHO 30 to 50%  of all cases of cancers are preventable.

Development of cancer in a person depends upon a combination of genetic makeup (genes) and his lifestyle. Genetic profile of a person is unchangeable but lifestyle can be modified so the exclusion of one risk factor in the form of lifestyle modification reduces the risk of developing cancer. For example, if a person has a family history of lung cancer he can reduce the risk of cancer by avoiding smoking.

Here are some important cancer prevention tips -

1. Stop Using Tobacco

smoking and cancer, how to quit smoking, how smoking causes cancer

According to WHO Tobacco kills more than 7 million people worldwide every year. Smoking causes 15 different types of cancers, lungs and heart diseases. Smokers are susceptible to cancer of the throat, oral cavity, larynx, kidney, bladder, oesophagus, stomach, liver, pancreas, cervix, bowel and various types of leukaemias. Cigarette contains over 4000 chemicals from which 70 to 80 chemicals cause cancers.

Carcinogens in cigarettes -
  • Nicotine
  • Arsenic
  • Lead
  • Acetaldehyde
  • Benzene
  • Ammonia
  • Carbon monoxide
  • Chromium
  • Acrylonitrile
  • Nickel
These carcinogens present in smoke damage our DNA and affect the genes which protect us from cancer and weakens our immune system to fight against diseases. Carbon monoxide present in cigarette smoke reduces the capacity of haemoglobin to carry oxygen and damages lungs. Now you may have understood how dangerous smoking is for your health and how to quit smoking helps in cancer prevention. If you can not completely stop smoking, you can reduce the number of cigarettes smoked and slowly quit smoking. You can take help of your doctor for alternative methods.

Tobacco Control Research Branch of the National Cancer Institute has created a website https://smokefree.gov/ to help people stop smoking.

Best Cancer Prevention Foods, Cancer prevention diet

If I ask how many of you people eat processed food? I know the answer to most of the people will yes. because all love testy processed food but do you know eating excessively processed food (Cake, biscuits, processed, processed red meat, meat products, bread) increases the risk of many diseases like cancer, Diabetes and cardiovascular. So you should reduce the intake of processed and fried food to prevent yourself from many deadly diseases.

                  Food rich in vegetables, fruits, legumes, whole grain and beans reduces the risk of cancer, that's why you should add vegetables and fruits to your daily diet. Vegetables and fruits contain antioxidants like vitamins (A, C and E),  beta-carotene and phytochemicals. These antioxidants neutralize the free radicals generated in our body during the various processes. Free radicals damage DNA in our body, thus plays a very important role in the development of cancer. Phytochemicals reduce the inflammation and growth of cancer cells.

Best Foood for Cancer Prevention

  • People who have been drinking alcohol for long periods can develop liver cirrhosis. Liver cirrhosis patients are more susceptible to liver cancer.
  • Excessive drinking also makes people obese because alcohol provides extra calories. Obesity increases the risk of various cancers.
