Nearly 50 Percent Cancer Cases Due to Unhealthy Lifestyle: Research

Nearly half of cancer cases in the United States can be blamed on lifestyle choices made by people, as per a new research published in a journal managed by the American Cancer Society. Pharmaceutical companies and medical research teams have been trying hard to fight cancer but the treatment still offers little help. Even when cancer patients survive, they suffer other health issues. Cancer has become a major health issue and researchers have repeatedly found that obesity, smoking, poor diet and other unhealthy lifestyle choices lead to cancer.

The study published in CA: A Cancer Journal for Clinicians has blamed smoking for 30 percent of all cancer related deaths in the United States. CDC data shows that smoking rate has declined in the recent years but obesity has witnessed an increase. The study team also noticed that people aren’t eating enough of fresh fruits and vegetables.

The study team added that nearly 45 percent of cancer deaths were caused by "modifiable" risk factors. The study team also found that 42 percent of diagnosed cancer cases can be linked to bad lifestyle choices. People need to eat healthy, exercise regularly and live in a clean and pollution-free environment.

"We thought it was time to redo those estimates," said Dr. Otis Brawley, the American Cancer Society's chief medical officer. Dr. Brawley is one of the study's authors.

The study team noted that 82 percent of lung cancer cases could be linked to smoking. Nearly 33 percent of liver cancer cases were linked to excess body weight. Being overweight also increased the risk of uterine cancer. 25 percent of liver cancer cases among men could be linked to alcohol consumption. Alcohol consumption was also linked to 12 percent of cancer cases among women. 95 percent of skin cancer cases were linked to excessive exposure to UV radiation from sunlight or tanning beds.

As per CDC data, cancer is the second most common cause of death in the United States. During 2016, 596,000 people died due to cancer.
