Risk Of Cancer With Obesity

Risk Of Cancer With Obesity

It has been all over the news recently that being overweight or obese can severely increase your risk of cancer, even now overtaking lung cancer. Most of my clients who come to me for my healthy eating and exercise plans want to lose body fat and lead a healthier lifestyle. One recent client lost over 4 stone and says he feels like a new person.

Being overweight or obese is a risk factor for several types of cancer. Although a higher weight may not necessarily cause cancer, maintaining a healthy weight is thought to be associated with a lower risk of many chronic diseases.

This country is becoming more like America by the day with people eating far too much processed foods and not doing enough exercise. More than two-thirds of American adults are overweight or obese and the UK is not far away! When a person is overweight or obese, it means that they have too much body fat in relation to lean body tissue, such as muscle. Many factors cause people to become overweight or obese, including genetic, hormonal, environmental, emotional, and cultural factors. People who are overweight or obese have a higher risk of many serious health conditions, including type II diabetes, high blood pressure, and heart disease. Being overweight or obese is also associated with an increased risk of cancer.

Several studies have explored why being overweight or obese may increase cancer risk and growth. People who are obese have more fat tissue that can produce hormones, such as insulin or estrogen, which may cause cancer cells to grow.


How your weight changes throughout your life may also affect your risk for cancer. Although more research is needed, studies have shown that the following factors can affect your cancer risk of cancer:

  • High birth weight is associated with higher cancer risk.
  • Weight gain during adulthood is consistently associated with an increased risk for several types of cancer.
  • Weight cycling (losing and regaining weight repeatedly) may also be a risk factor.
  • Research suggests that maintaining a healthy weight is associated with a lower risk of cancer and a lower risk of cancer recurrence (when cancer comes back after treatment) in cancer survivors.

Some types of cancer appear to be closely linked to weight, although this association has not been proven for all cancers. Some cancers in which overweight has been found to be consistently associated with increased risk are:

  • Breast (in women who have been through menopause)
  • Colon and rectum
  • Uterine
  • Kidney
  • Esophageal
  • Pancreatic
  • Endometrium (lining of the uterus)
  • Thyroid
  • Gallbladder

Although more evidence is needed, being overweight has been associated with other cancers:

  • Ovarian
  • Cervical
  • Liver
  • Non-Hodgkin lymphoma
  • Multiple myeloma
  • Prostate

Obesity is often measured with body mass index (BMI), the ratio of a person’s weight and height, and waist measurements. A normal BMI is between 18.5 and 24.9. A BMI between 25 and 29.5 is considered overweight, while a BMI of 30 or higher is obese. In addition, people with larger waist measurements have a higher risk of various diseases, such as heart disease. A normal waist measurement is under 40 inches for men and under 35 inches for women.

To control weight gain, it is important to be aware of what you eat and how much you exercise and to make healthy choices about what you eat and drink. As I have said over and over again, eat a complex carbohydrate and a protein source with every meal and plenty of vegetables and salad. Eat little and often through out the day, and avoid sugar! Also make sure you exercise, even if it’s just a brisk walk for 30-40 minutes 4-5 times a week.



So my top tips for this week are:

  • Avoid processed food and fast food, especially take aways!
  • Eat little and often, 6-8 small meals a day. This will increase your metabolism and help you lose body fat
  • Exercise at least 4 times a week, even if it’s just a fast brisk walk.
  • Avoid sugar, especially white carbohydrates
