Summary
Soybeans and their compounds, isoflavones, may offer a protective effect against prostate cancer. Further multiethnic studies are recommended to confirm these findings.
Area of Science:
- Oncology
- Nutritional Science
- Epidemiology
Background:
- Prostate cancer incidence varies geographically, suggesting environmental and dietary influences.
- Asian populations exhibit lower prostate cancer rates, potentially linked to high vegetable intake, including soy products.
Purpose of the Study:
- To review existing epidemiological and laboratory research on the association between soy, isoflavones, and prostate cancer.
- To highlight the potential prophylactic role of soy isoflavones in prostate cancer prevention.
Main Methods:
- Review of epidemiological studies examining dietary patterns and prostate cancer.
- Analysis of laboratory research investigating the effects of soybeans and isoflavones.
- Synthesis of data on soy consumption and prostate cancer incidence.
Main Results:
- Soybean consumption, rich in isoflavones (genistein, daidzein, glycitein, equol), is associated with lower prostate cancer incidence.
- Isoflavones demonstrate a potential prophylactic effect against prostate cancer development.
Conclusions:
- Dietary factors, particularly soy consumption, may play a role in prostate cancer prevention.
- Further large-scale, multiethnic epidemiological studies are needed to validate the protective effects of soy and isoflavones.

02:59Cancer 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.

03:03mTOR Signaling and Cancer Progression
The mammalian target of rapamycin or mTOR protein was discovered in 1994 due to its direct interaction with rapamycin. The protein gets its name from a yeast homolog called TOR. The mTOR protein complex in mammalian cells plays a major role in balancing anabolic processes such as the synthesis of proteins, lipids, and nucleotides and catabolic processes, such as autophagy in response to environmental cues, such as availability of nutrients and growth factors.

02:57Targeted Cancer Therapies
The targeted cancer therapies, also known as “molecular targeted therapies,” take advantage of the molecular and genetic differences between the cancer cells and the normal cells. It needs a thorough understanding of the cancer cells to develop drugs that can target specific molecular aspects that drive the growth, progression, and spread of cancer cells without affecting the growth and survival of other normal cells in the body.

01:28Menopause
Menopause, a natural biological process marking the end of a woman's fertility, typically occurs between the fifth and sixth decade of life. This phase is characterized by the exhaustion of the ovarian follicle pool, leading to less responsive ovaries despite the high levels of Follicle Stimulating Hormone (FSH) and Luteinizing Hormone (LH). The consequential decrease in estrogen production results in symptoms like hot flashes, heavy sweating, headaches, hair loss, muscle pains, vaginal...
