Why non smoker are still able to contract lung cancer and what's its prevention?
Cigarette smoking is the most common cause of lung cancer. However, there are non-smokers who still contract lung cancer due to Radon. Radon is a radioactive gas released from the normal decay of the elements uranium, thorium, and radium in rocks and soil. It is an invisible, odorless, tasteless gas that seeps up through the ground and diffuses into the air. People who live in ground floor has higher contact with Radon, therefore it is important to open the windows to have good ventilation in the house. If we are traveling and away from home for long duration, the amount of Radon trap in the house/rooms will be very high due to poor ventilation. Therefore, upon returning from traveling, we should open the windows immediately to allow good ventilation in the house/room.

30%of non-smoker get lung cancer through secondhand cigarette smoke. What is the distance to avoid secondhand cigarette smoke? There is no safe distance as the cigarette smoke will remain on the sofa, curtain and clothes of smoker. The smoker might ventilate the room or house after smoking. However, non-smoker/children will touch the chemical that is remain on the sofa, curtain or in contact with the smoker. Separating smokers from nonsmokers, cleaning the air, and ventilating buildings cannot completely eliminate exposure to secondhand smoke

The third type of people that are high risk of lung cancer are miners. When working underground, miners can also be exposed to other substances that might affect lung cancer risk, such as radon.
Is diet able to build up immunity and prevent cancer?
A person will not have cancer as long as they have a strong immune system. Cancer takes a long time to develop and a person's immune system has to be malfunction for the cancer cell to multiply. It takes 6-8 years for breast cancer to grow from one cell to the size of 1 cm. It takes about 10-20 years for a person to develop lung cancer. For example, a person detected lung cancer at the age of 50 years old, it means that this person started having lung cancer at 30 years old. Therefore, prevention of cancer through the right nutrition is important. A lot of young people did not take care of their health when they are young and eat fried food, oily food, processed food and sleep late. However, prevention of diseases starts from young.
Can we detect cancer through x-rays and what happens when we take too much x-rays?The medical machine that we have is not able to detect cancer cell at the very beginning of cancer formation. The most advance machine can only detect tumors with diameters 1 mm. However, this 1 mm tumor is made up of at least 1 million cancer cells! By the time cancer is detected 2/3 of the cancer stage has passed. X-rays and gamma rays are known human carcinogens (cancer-causing agents). http://www.cancer.org/cancer/cancercauses/radiationexposureandcancer/xraysgammaraysandcancerrisk/x-rays-gamma-rays-and-cancer-risk-do-xrays-and-gamma-rays-cause-cancer
What are the food that can boost immune system?
Scientists have studied the types of food that have highest Antioxidant, Phytochemical and Polysaccharides. Most of the disease fighting nutrients are in the fruits and vegetables. Have at least 2 meals of vegetarian out of 3 meals. Instead of having 4 meat dishes and 1 vege dish in a meal, we should eat more plant food 4 vege dishes and 1 meat dish. Diet that are high in animal protein can increase the risk of cancer. Meat contains a harmful substance (hormone) that causes cancer. Plant based Nutrition helps prevent cancer by boosting immunity. We can also increase food that are high in Polysaccharides. Lastly, live a healthy lifestyle - get enough exercise, get sufficient sleep and rest and stay positive.
How should we take our breakfast as we always hear that breakfast is the most important meal of the day?
Any food and nutrients that we eat in the morning are easily absorb by our body. We should drink plenty of water early in the morning as our body is performing the function of detoxification when we are sleeping at night. Food that are high in fiber is good as it acts like a broom to clean the intestine. Do not take any oily food, meat, ham, bacon and sausages. Ham, Bacon and Sausages contain nitrosamine, a carcinogen. A person can only take a maximum 300mg of cholesterol. 2 chicken eggs for breakfast have already exceeded the daily cholesterol limit. Take the whole fruit instead of fruit juice. Juices without the fiber are high in sugar.
