5 of the most aggressive types of cancer: can they reduce their risk?

These aggressive cancers have very low survival rates. But there is also good news: doctors believe that with a healthy lifestyle, about half of all cancers can be avoided. In the list of such tumors – pancreatic cancer, liver cancer, lung cancer, brain cancer, blood cancer.
Pancreatic cancer: a worse prognosis tumor. For both functions, it has a special fabric. In the tissue that produces digestive juices, most malignant tumors develop.Survival: pancreatic carcinoma has the lowest survival rates among all types of cancer of the five-year border reaching only about 9 percent of patients.
risk factors that can be avoided: smoking and passive smoking, overweight, type 2 diabetes.In many cases, cancer in the organ develops from liver cirrhosis, but also chronic liver inflammation associated with hepatitis B or non -alcoholic fatty hepatitis of the liver can also cause cancer. Classical chemotherapy with its strong toxins may not be suitable for diseased liver. Surgery is possible only if there is a healthy tissue in the organ, and in three of the four cases, liver cancer cannot be surgically removed. With liver carcinoma after successful initial treatment, the tumor often appears again.
Survival: Five -year survival in liver cancer is an average of 12 percent.
risk factors that can be avoided: alcohol, toxic substances, drugs. About 80 percent of patients are diagnosed with non -plain cell lung cancer, 20 percent suffer from fine -cell lung cancer.
The initial stage of lung cancer does not cause special changes and unpleasant sensations in the person. Therefore, in many cases, it turns out to be late that, in turn, it is the cause of the low probability of recovery. This is especially typical for small -cell cancer that grows rapidly and spreads: most patients are diagnosed in the fourth stage of the disease.Risk factors that can be avoided: smoking, exhaust gases, dust, smog.
brain cancer: rare and deadly. there are several subspecies with very different indicators of treatment efficiency. For example, children have tumors other than adults. In this case, the effectiveness of treatment reaches more than 90 percent. In adults, the most common brain tumor is the most aggressive – glyoblastoma.
Survival: Five -year survival for all brain tumors is slightly over 20 percent, but for glyoblast, the forecasts are much worse: the average survival time is 15 months from the moment of diagnosis. chronic. with leukemia immature blood cells multiply uncontrollably. If there are many, they displace healthy blood cells. There are acute and chronic leukemia. Acute forms are sudden diseases that can lead to death for several weeks, while chronic leukemia is much slower. Also for blood cancer is a high risk of recurrence. In adults, acute forms of leukemia have the most unfavorable prognosis.
risk factors that can be avoided: lifestyle does not affect leukemia. X -ray or radioactive rays probably contribute to the formation.
