Preventing bladder cancer.
Preventing breast cancer.
Preventing diabetes.

Insufficient Evidence to Rate Effectiveness for...

Cervical cancer. Some limited evidence suggests that eating more tomatoes is associated with a lower chance of developing cervical cancer.
Cancer of the colon and rectum (colorectal cancer). Research findings about the effect of tomatoes on colorectal cancer risk disagree. Some studies find that tomatoes or tomato-based products may help to reduce the chance of getting this type of cancer, but other studies that some scientists think are better designed find no benefit.
Stomach cancer. So far, research studies do not agree on whether or not tomatoes or tomato-based products can help prevent stomach cancer.
Lung cancer. There are mixed findings about the effect of eating tomatoes on lung cancer. Some research concludes that tomatoes or tomato-based products can help prevent lung cancer. But these studies have been criticized because they didn't take people's smoking behavior into account. Higher quality, large-scale studies do not show any link between eating tomato products and lung cancer risk.
Ovarian cancer. Some research suggests that eating more tomato or drinking more tomato juice does not seem to prevent ovarian cancer; however, consuming tomato sauce two or more time per week does seem to lower the risk of getting ovarian cancer. Other evidence suggests that increased dietary intake of lycopene, particularly from tomato sauce, is associated with a reduced risk of ovarian cancer in younger (pre-menopausal) women.
Pancreatic cancer. Study results disagree about the effect of tomato on pancreatic cancer risk. One large-scale study shows that eating tomato or tomato-based products does not seem to prevent pancreatic cancer. However, other studies suggest that raw tomato intake, and high tomato intake in general, is associated with a reduced chance of developing pancreatic cancer.
