Cancer Prevention

Cancer Prevention

Several factors can increase the risk of cancer in an individual. About 50% of cancer cases can be prevented by adopting a healthy lifestyle, regular exercise, eating healthy, and following a modest cancer prevention diet. Epidemiological studies have consistently shown that populations with vegetable and fruit-rich diets have reduced the incidence of cancer. On the other hand, populations who have a diet rich in animal fat, red meat, junk food, or high calories are predisposed to cancer.

Psychoneuroimmunology: Diabetes and Cancer

Psychoneuroimmunology: Diabetes and Cancer

Chronic stress has been linked to both the onset and progression of serious health conditions, including Type 2 diabetes and cancer. Type 2 diabetes, a widespread chronic illness, is closely associated with obesity and insulin resistance, both of which often worsen under stress. Studies indicate that men experiencing high levels of chronic stress face a 45% higher risk of developing diabetes compared to those with minimal stress. Stress triggers physiological responses that elevate blood...

Loss of Tumor Suppressor Gene Functions

Loss of Tumor Suppressor Gene Functions

Tumor suppressor genes are normal genes that can slow down cell division, repair DNA mistakes, or program the cells for apoptosis in case of irreparable damage. Hence, they play an essential role in preventing the proliferation of damaged cells.
When the tumor suppressor genes develop mutations or are lost, cells start growing out of control, leading to cancer. However, a single functional copy of the tumor suppressor gene is enough for the cells to maintain their normal functions and cell...

What is Cancer?

What is Cancer?

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.
Although people have known about cancer for centuries, it was only in 1761 that Giovanni Morgagni of Padua performed a detailed autopsy of patients who died from...

Summary

Maintaining a healthy weight is crucial for cancer prevention. Evidence shows that weight loss can significantly reduce the risk of developing many common cancers.

Area of Science:

Oncology
Public Health
Epidemiology

Background:

Obesity and weight gain are recognized risk factors for numerous cancers.
The International Agency for Research on Cancer (IARC) previously assessed these links in 2002.
Updated evidence is needed to refine cancer prevention strategies.

Purpose of the Study:

To review and update the scientific evidence linking obesity, weight gain, and weight loss to major cancer types.
To emphasize the temporal relationship between weight changes and cancer development.
To assess the implications of weight management for cancer prevention.

Main Methods:

Systematic review and evidence synthesis of recent scientific literature.
Analysis of epidemiological data on cancer incidence and body mass index (BMI).

Evaluation of the time course of cancer development in relation to weight status.

Main Results:

Significant associations between excess body weight and increased risk for several common cancers were confirmed.
The time lag between weight gain and cancer diagnosis was considered.
Evidence suggests that intentional weight loss can mitigate cancer risk.

Conclusions:

Weight control is a critical modifiable factor for cancer prevention.
Weight loss interventions hold potential for reducing the burden of common cancers.
Further research into the mechanisms and optimal strategies for weight management in cancer prevention is warranted.
