Lower cancer risk in large families
Larger the family, lower the cancer risk, states a new study based on data collected from 178 countries. 
This link was independent of income, age and urbanisation of the family; the family size also included members of the extended family in the household. Researchers found that the protective effect of a large family was stronger in men than in women. The study suggested that family life can provide positive emotional environments that can boost a person’s resistance to diseases, including cancer. It is based on the premise that family members support one another in following a healthy lifestyle.
Obesity surgery may cut heart attack risk in diabetics
Diabetics who are severely overweight might be able to prevent heart attacks and strokes 
by undergoing surgery, states a new study. While it has been established that weight loss surgery can help people better control health conditions like diabetes and high blood pressure, the new research indicates that such surgery could also mean fewer heart attacks and strokes. The team found that severely obese patients were 40 percent less likely to suffer a heart attack or stroke over five years after the surgery.
