Cancer and tumors can be caused by obesity, obesity is the accumulation of fat is very high, thus making weight loss is beyond ideal. some complications can lead to death
Overweight and obesity are a global health problem. In the United States, known for more than 69% of adults aged 20 years or older, were overweight or obese. Something similar is also found in the UK, where about 62% of people aged over 16 are known to have overweight or obese.
Obesity and increased risk of cancer
In addition, being overweight can also increase the risk of serious health problems, such as heart disease, diabetes, high blood pressure, and stroke. Previous research has also suggested that overweight and obesity can increase the risk of cancer.
Now, researchers led by a Dr Krishnan Bhaskaran, of the London School of Hygiene & Tropical Medicine in the UK, has conducted studies to determine the relationship between body mass index (BMI) and cancer.
The effect of BMI on cancer is quite varied
To reach their findings, the researchers reviewed data from general practitioner records obtained from UK’S Clinical Practice Research Datalink. From this, they identified 5.24 million people aged 16 years or more cancer-free, and have been followed for an average of 7.5 years. The research team analyzed the BMI of participants and measure themselves against the risk of 22 common types of cancer.
The analysis showed that the 166 955 participants from 22 developing one of these cancers. The researchers found that the Body Mass Index or BMI associated with 17 of the 22 cancers, and 10 of them are even associated very strong.
They found that each increase of 5 kg / m2 in BMI was associated with a higher risk of cancer following:
Rahim (62% increased risk).
The gallbladder (31% increased risk).
Kidney (25% increased risk).
Cervical (10% increased risk).
Thyroid (9% increased risk).
Leukemia (9% increased risk).
The researchers also found that a high body mass index is associated with the risk of liver cancer by 19%, colon cancer by 10%, amounting to 9% of ovarian cancer, and breast cancer by 5%.
The research team noted that all the increase in the risk varies considerably depending on the Body Mass Index (BMI), gender, and menopausal status. In fact they found some evidence that high BMI is also associated with a lower risk of prostate cancer and premenopausal breast cancer.
“There is a lot of variation in the effect of BMI on different cancers,” said Dr. Bahskaran.
For example, the risk of cervical cancer increased substantially in body mass index higher. For other cancers, we see an increase of more moderate, or no effect at all for some types of cancer such as breast cancer in young women before menopause. This variation tells us BMI must affect cancer risk through a number of different processes, depending on the type of cancer. ”
In an editorial related to the study, Dr Peter Campbell, from the American Cancer Society, noted there is “sufficient evidence” that overweight and obesity is one of the causes of cancer, and “further research is not required to justify, or even demand , policy changes aimed at curbing excess weight and obesity. ”
