Types of Cancer linked to Obesity
In 2014, about 630,000 people in the U.S. were diagnosed with overweight and obesity-related cancer. Science shows that having too much body fat has been linked with an extremely high risk for 13 types of cancer, including:
According to a study, being overweight, as compared to having a normal BMI, was associated with a 21% increased risk of liver cancer. On the other hand, there was an 87% increased risk of liver cancer for someone with obesity. The more a person is obese, the higher the risk.
When a person is overweight or obese, he is nearly twice as likely have the most usual type of kidney cancer which is the renal cell cancer than people with normal weight.
There is a significant spike in breast cancer risk for women with obesity after menopause. Hormones such as estrogen allow certain breast cancers to develop. After menopause, the ovaries stop releasing estrogen, so the levels in the body decline. Men who are obese are also at risk for breast cancer, although rarely.
A 2014 study indicated that 7% of ovarian cancer cases in the United Kingdom had been linked to obesity. A higher BMI slight increases the risk for ovarian cancer, especially in women who have never undergone hormone replacement therapy.
This occurs in the rectum or colon. There is a 30% chance that people who are obese will develop colorectal cancer compared to normal-weight people.
The significant risks of developing colorectal cancer include an unhealthy diet, lack of physical exercise, and being insufficient in necessary vitamins and minerals, such as calcium.
It is also found that obesity was associated with a statistically significant 50–60 percent rise in the incidence of pancreatic cancer.
Due to increasing obesity rates in the U.S, pancreatic cancer is predicted to become the second-deadliest cancer by 2030 and that weight loss can interrupt this phase in its early stages, according to a recent study led by researchers at the Yale Cancer Center (YCC).
Obesity tends to be a risk factor for the growth of thyroid cancer in women.
Higher BMI is linked with a slight increase in the risk of thyroid cancer by ten percent.
In women, the increased risk of gallbladder cancer is more common than in men.
Research has shown that the probability of gallbladder cancer was 15 and 66 percent higher for people who were overweight and obese, respectively, than those with average weight.
Within the skull, this cancer happens when a tumor grows on membranes covering the brain and spinal cord.
A higher BMI is a strong culprit in the development of meningioma—increasing by about 50 percent in people who are obese and about 20 percent in people who are overweight.
Obesity is a risk factor for the growth and mortality from many types of cancer. Many studies show that weight loss can lessen the risk of some cancer types.
For instance, obese and overweight people who deliberately lose weight have decreased levels of some cancer-related hormones, such as insulin, estrogens, and androgens. If you bear excess pounds, losing even a slight amount of weight has health benefits and is a healthy way to start.
