Summary
Rising global obesity is linked to increased cancer risk. Excess weight contributes significantly to cancer cases, impacting prognosis and increasing adult cancer risk from childhood obesity.
Area of Science:
- Public Health
- Epidemiology
- Oncology
Background:
- Global prevalence of overweight and obesity is increasing in adults and children.
- In France, 49% of adults were overweight and 17% obese in 2015.
- Overweight and obesity are established risk factors for 13 cancer types.
Purpose of the Study:
- To highlight the link between excess weight and cancer incidence and prognosis.
- To quantify the burden of cancer attributable to excess weight in France.
- To emphasize the role of diet and physical activity in obesity prevention.
Main Methods:
- Analysis of epidemiological data on overweight and obesity prevalence.
- Review of International Agency for Research on Cancer (IARC) evaluations on cancer risk factors.
- Estimation of cancer cases attributable to excess weight in France.
Main Results:
- In France, 5.4% of cancer cases (18,600) in 2015 were attributed to excess weight.
- Specific cancer burdens include colon (3400), kidney (2600), breast (4500), and endometrial (2500).
- Obesity is associated with poorer prognosis in breast and colon cancers.
Conclusions:
- Excess weight is a significant contributor to cancer incidence and mortality.
- Obesity prevention through balanced diet and physical activity is crucial.
- Addressing childhood obesity is vital to reduce future adult cancer risk.

1.2K
The Body Mass Index (BMI) is a numerical value derived from a person's weight and height, used to categorize individuals into weight ranges. It is calculated using the formula: weight in kilograms divided by height in meters squared. Obesity is a health condition characterized by excessive accumulation of adipose tissue that poses health risks, often diagnosed with a BMI ≥ 30. This excess fat storage occurs when surplus dietary calories are converted into triglycerides and stored in...

01:21Drug Dosing: Obese Patients
238
In the United States, obesity is a prominent concern. It is linked to heightened mortality rates due to increased occurrences of conditions such as hypertension, atherosclerosis, coronary artery disease, and diabetes compared to nonobese individuals. A patient is classified as obese if their actual body weight surpasses the ideal or desirable body weight by 20%, based on Metropolitan Life Insurance Company data. Ideal body weights consider average weights and heights for males and females...

01:25Pharmacokinetics in Obese Patients: Drug Absorption and Distribution
260
Obesity significantly alters the pharmacokinetic processes of drug absorption and distribution, presenting unique challenges in medical treatment. The increased fat tissue and decreased lean muscle in obese individuals can significantly affect how drugs are absorbed into the body and distributed across different tissues. This alteration can lead to variances in the effectiveness and safety of medications, necessitating adjustments in dosing or drug selection for obese patients.One notable...

01:20Pharmacokinetics in Obese Patients: Drug Metabolism and Excretion
175
Drug metabolism, a critical process in the liver, involves two primary phases: Phase I reactions and Phase II conjugation. Obesity introduces significant alterations in this metabolic process, primarily due to fatty infiltration of the liver, leading to conditions such as nonalcoholic fatty liver disease (NAFLD). This condition can modify the activities of both Phase I and II enzymes, impacting how drugs are metabolized in obese patients.Phase I metabolism sees variable effects across...

Cancers arise due to mutations in genes involved in the regulation of cell division, which leads to unrestricted cell proliferation. Modern science and medicine have made great strides in the understanding and treatment of cancer, including eradicating cancer in some patients. However, there is still no cure for cancer. This is largely due to the fact that cancer is a large group of many diseases.

14.1K
Cells and tissues must meticulously coordinate their activities for the normal functioning of the human body. Therefore, they exhibit socially responsible behavior - resting, growing, dividing, differentiating, or dying - for the organism’s benefit. Cancer arises when cells divide uncontrollably and invade other tissues or organs.
