23 March 2026 Punjab Khabarnama Bureau : A new study suggests that avoiding five major lifestyle risk factors could prevent up to half of all Cancer cases, highlighting the powerful role that everyday habits play in long-term health.
Researchers found that several common behaviors significantly increase the risk of developing different types of cancer. By reducing exposure to these risks, individuals may dramatically lower their chances of developing the disease.
The study focused on five key lifestyle factors that are strongly linked to cancer risk: smoking, excessive alcohol consumption, unhealthy diet, physical inactivity, and obesity. Scientists say these factors contribute to the development of several common cancers, including lung, breast, colorectal, and liver cancers.
According to the researchers, smoking remains the single largest preventable cause of cancer worldwide. Tobacco contains thousands of harmful chemicals that damage cells and increase the likelihood of cancerous growths.
Alcohol consumption is another important factor. Regular or heavy drinking has been linked to cancers of the liver, mouth, throat, and breast. Limiting alcohol intake can significantly reduce this risk.
Diet also plays a crucial role. Diets high in processed foods, red meat, and sugar but low in fruits, vegetables, and fiber may contribute to cancer development. Experts recommend balanced meals rich in plant-based foods to support long-term health.
Physical inactivity and obesity were also highlighted in the study. Lack of regular exercise and excess body weight can disrupt hormonal balance and increase inflammation in the body, both of which are linked to higher cancer risk.
Health experts emphasize that small, consistent lifestyle improvements can have a powerful impact on cancer prevention. Regular exercise, maintaining a healthy weight, avoiding tobacco, limiting alcohol, and following a nutritious diet are key strategies.
While not all cancers can be prevented, researchers say that adopting healthier habits can significantly reduce overall risk and improve quality of life.
The study reinforces the importance of preventive healthcare and public awareness about lifestyle-related diseases. Experts believe that community education and healthier environments could help millions of people reduce their cancer risk.
Summary :
A study suggests avoiding smoking, excessive alcohol, unhealthy diet, inactivity, and obesity could prevent up to 50% of cancer cases, highlighting the major role lifestyle choices play in disease prevention.
