Based on NIH | Does eating rice increase the risk of testicular cancer?

Eating rice is not known to increase the risk of testicular cancer. Current medical references list factors like undescended testicle (cryptorchidism) and a prior history of testicular cancer as key risks, and they do not include rice or general diet as established causes. ^{[1] [2]} Major clinical summaries also note that testicular cancer risk is not linked to specific habits or lifestyles such as typical dietary patterns. ^[3]

What science says about testicular cancer risks

• Well‑recognized risk factors: An undescended testicle and having had testicular cancer before are consistent, important risks. ^{[1] [2]}
• Other possible risks: Family history and certain chemical exposures are sometimes mentioned, but evidence is limited and the overall cause is still unclear. ^[4]
• Lifestyle and diet: Authoritative overviews indicate testicular cancer is generally not tied to lifestyle habits, which includes routine foods like rice. ^[3]

Diet, rice, and cancer: separating facts

• Rice specifically and testicular cancer: There is no established evidence that eating rice raises testicular cancer risk. Reviews of adolescent and adult factors consider diet unlikely to increase testicular cancer risk. ^[5]
• Glycemic index and cancers in general: Some research links high glycemic index or glycemic load diets to higher risk of certain cancers (for example, colon, pancreas, or prostate), but not testicular cancer in large, mixed‑cancer analyses. ^[6] These findings are inconsistent across cancers and do not identify rice as a testicular cancer risk. ^[6]
• Whole grains and overall health: Choosing whole‑grain options like brown, black, red, or wild rice supports general health and may help reduce risk of some cancers, but this is about overall dietary patterns rather than testicular cancer specifically. ^[7]

Practical guidance for reducing overall cancer risk

While rice itself is not implicated in testicular cancer, these broad habits support cancer prevention and men’s health:

• Maintain a balanced diet rich in vegetables, fruits, legumes, and whole grains. ^[8]
• Keep a healthy weight and stay physically active, which benefit overall cancer risk profiles even if not specific to testicular cancer. ^[8]
• Know personal risks: If you had an undescended testicle or prior testicular cancer, your risk is higher and regular follow‑up is advisable. ^{[1] [2]}

When to seek medical attention

• New testicular changes deserve prompt evaluation. Any new lump, swelling, heaviness, or persistent ache in a testicle should be checked by a clinician, regardless of diet. Most causes are benign, but early assessment is important. ^[1]

Bottom line

• There is no credible evidence that eating rice increases testicular cancer risk. ^{[5] [3]} The strongest known risk factors relate to testicular development and prior cancer history, not common dietary items. ^{[1] [2]}
