Bleeding is typically divided into two main types: upper gastrointestinal bleeding and lower gastrointestinal bleeding. [2] Causes of upper GI bleeds include: peptic ulcer disease, esophageal varices due to liver cirrhosis and cancer, among others. [3] Causes of lower GI bleeds include: hemorrhoids, cancer, and inflammatory bowel disease among ...
Hepatocellular carcinoma is the most common primary liver cancer, and the most common cause of death in people with cirrhosis. [153] Screening using an ultrasound with or without cancer markers such as alpha-fetoprotein can detect this cancer and is often carried out for early signs which has been shown to improve outcomes.

Some substances cause cancer primarily through their physical, rather than chemical, effects on cells. [32] A prominent example of this is prolonged exposure to asbestos, naturally occurring mineral fibers which are a major cause of mesothelioma, which is a cancer of the serous membrane, usually the serous membrane surrounding the lungs.

Hepatocellular carcinoma (HCC [1]) is the most common type of primary liver cancer in adults and is currently the most common cause of death in people with cirrhosis. [2] HCC is the third leading cause of cancer-related deaths worldwide. [3]
Primary liver cancer is globally the sixth-most frequent cancer and the fourth-leading cause of death from cancer. [7] [10] In 2018, it occurred in 841,000 people and resulted in 782,000 deaths globally. [7] Higher rates of liver cancer occur where hepatitis B and C are common, including Asia and sub-Saharan Africa. [3]
Viral hepatitis, primarily hepatitis B and hepatitis C, remains a leading cause of liver cirrhosis and liver cancer worldwide, despite advances in antiviral therapies and vaccination efforts. [50] Additionally, recent studies have highlighted lean steatotic liver disease (SLD), a subset of NAFLD, affecting over 12% of U.S. adults even in the ...
Ulceration can cause bleeding that can lead to symptoms such as coughing up blood (lung cancer), anemia or rectal bleeding (colon cancer), blood in the urine (bladder cancer), or abnormal vaginal bleeding (endometrial or cervical cancer). Although localized pain may occur in advanced cancer, the initial tumor is usually painless.
Cancer of the stomach, also called gastric cancer, is the fourth-most-common type of cancer and the second-highest cause of cancer death globally. [2] Eastern Asia (China, Japan, Korea, Mongolia) is a high-risk area for gastric cancer, and North America, Australia, New Zealand and western and northern Africa are areas with low risk. [5]
