A new study found a link between men's height and their risk level for advanced prostate cancer, with tall men experiencing a 20% increased risk. Additionally, researchers discovered that fruit and vegetable consumption, particularly vitamin C and lycopene, may reduce the risk of stomach cancer by up to 45%.
Researchers found that a specific glycoprotein, O-glycans capped with alpha 1,4-linked N-acetylglucosamine, blocks H. pylori's ability to synthesize cholesterol, leading to cell death and potential treatment for stomach ulcers and cancer. The study suggests a natural defense mechanism against H. pylori infection.
Researchers found a significant association between H. pylori infection and reduced risk of esophageal adenocarcinoma, but a two-fold increased risk of squamous-cell carcinoma. Gastric atrophy was not linked to disease risk, suggesting an alternative pathway from H. pylori to cancer.
A recent report shows a significant decline in stomach cancer rates across Europe, with falls seen in younger and middle-aged populations. The downward trend is attributed to improved diet, better food preservation, reduced Helicobacter pylori infection, and lower smoking rates.
Researchers found that calcium supplements reduced the risk of colorectal cancer recurrence only among individuals with baseline vitamin D levels above the median. Serum vitamin D levels were also associated with reduced adenoma recurrence among individuals taking calcium supplements.
Researchers found that Hedgehog's signal is required for cancer growth in the digestive tract. A plant-derived chemical called cyclopamine blocked this signal, killing tumors in mice without harm.
The report analyzed data from 22 countries and 42 types of cancer, showing average five-year survival rates ranging from 94% for lip cancer to less than 4% for pancreatic cancer. Regional variations were found, with some Eastern European countries having lower survival rates and western Europe performing better.
A new chemotherapy regimen combining docetaxel with cisplatin and 5-Fluorouracil has been shown to significantly improve survival rates in late-stage stomach cancer patients. The study found a nearly 80% higher chance of tumor shrinkage and a reduced risk of cancer growth.
A study has identified specific combinations of H. pylori bacterial strain and host genetic variations that increase the risk of stomach cancer in infected individuals. These findings suggest that personalized genotyping can help identify high-risk individuals, who may benefit from targeted H. pylori eradication treatment.

In developed countries, cancer mortality is more than twice as high as in developing countries due to factors like tobacco consumption and Western nutrition. In contrast, up to 25% of malignancies in developing countries are caused by infectious agents, whereas chronic infections account for only 8% in developed nations.
Scientists from Johns Hopkins Medicine have discovered that sulforaphane, a compound found in broccoli, kills the bacterium Helicobacter pylori, which causes stomach cancers and ulcers. The findings suggest that dietary intake of vegetables containing sulforaphane could relieve infection and have significant public health implications.
A recent study published by researchers at the University of Southern California found that polyphenols in tea may be associated with a lower risk of gastric and esophageal cancer.
