Colorectal cancer is the second most common cancer in the world. It can metastasize and spread to other body parts. Colorectal cancer is dangerous and can be life-threatening. But death rate from colorectal cancer has dropped in the recent years, thanks to advance screening techniques and better colorectal treatment options.
Colorectal cancer is also known as bowel cancer, colon cancer, or rectal cancer. Colorectal cancer begins as an abnormal growth of cells in the inner lining of the colon or rectum. This abnormal growth is called a polyp.
Some types of polyps can change into cancer over the course of several years. But it does not mean that all polyps have the tendency to become cancerous. The chance of changing a polyp into colorectal cancer depends on the type of polyp that grows.
Colorectal cancer can affect men and women equally. However, studies have proven that men might develop it at a younger age.
There is no definite cause of colorectal cancer, but old age and certain lifestyle factors can increase colorectal cancer risk. Some of these colorectal cancer risk factors include the following:
A majority of colorectal cancers are adenocarcinoma. If you have been diagnosed with colorectal cancer, there are 95 percent chances that it is an adenocarcinoma. But there are some other types of colorectal cancer such as carcinoid, gastrointestinal stromal, lymphomas, and sarcomas.
There are no early signs of colorectal cancer, but once it grows, the patients may experience the following colon cancer symptoms:
Stomach cancer, also known as gastric cancer, is the fifth most common cancer worldwide. This disease is a result of the growth of cancerous and malignant cells in the inner lining of the stomach.
Stomach cancer does not grow overnight as this disease usually grows slowly over many years. Some pre-cancerous changes take place before true cancer actually develops. But these early changes rarely result in any symptoms and therefore, often go undetected in the early stage when it is most easy to treat it.
Gastric cancer can grow through the wall of the stomach and invade nearby organs. It can easily spread to the lymph vessels and lymph nodes. In an advanced stage, it can travel through the bloodstream and spread or metastasize to organs such as the liver, lungs, and bones. Usually, people diagnosed with stomach cancer have either experienced metastasis already or eventually develop it.
Stomach cancer should not be confused with other cancers in the abdomen or esophageal cancer. Some other cancer can also occur in the abdomen, including cancer of the large and small intestine, liver or pancreas. These cancers may have different symptoms, outlook, and options for treatment.
Some other types of stomach cancers include squamous and small cell carcinoma and leiomyosarcoma. These cancers are very rare.
There is no single, definite cause behind stomach cancer. However, several stomach cancer risk factors have been identified that could potentially lead to the formation to a tumor in the stomach. Some of these stomach cancer causes or risk factors include:
There can be several early stomach cancer symptoms. However, the signs of stomach cancer could be present because of some other underlying condition as well. Unfortunately, this is the main reason why it is difficult to make stomach cancer diagnosis at an early stage.
Some of the early stomach cancer symptoms may include:
But just experiencing indigestion or heartburn after a meal does not really mean that you have cancer. Although, if you experience these symptoms a lot, talk to your doctor, who can decide whether to conduct further tests or not.
As advanced gastric cancer grow, you may experience more serious signs of stomach cancer, including the following:
