Carcinoid syndrome occurs when a rare cancerous tumor called a carcinoid tumor secretes certain chemicals into your bloodstream, causing a variety of symptoms. Carcinoid tumors occur most commonly in your gastrointestinal tract, in your lungs or, rarely, in the ovaries.
Because carcinoid tumors generally grow slowly, you typically wouldn’t experience symptoms until they’re quite advanced. You might discover you have carcinoid cancer through a test for an unrelated disease or condition.
Treatment for carcinoid syndrome usually involves treating the cancer. However, because most carcinoid tumors don’t cause carcinoid syndrome until they’re advanced, a cure may not be possible. In those cases, medications may relieve your symptoms of carcinoid syndrome and make you more comfortable.
The signs and symptoms depend on which chemicals your carcinoid tumor secretes into your bloodstream. The most common carcinoid syndrome symptoms include:
Colon cancer is cancer of the large intestine (colon), the lower part of your digestive system. Rectal cancer is cancer of the last 6 inches of the colon. Together, they’re often referred to as colorectal cancers. About 112,000 people are diagnosed with colon cancer annually, and about 41,000 new cases of rectal cancer are diagnosed each year, according to the American Cancer Society. Most cases of colon cancer begin as small, noncancerous (benign) clumps of cells called adenomatous polyps. Over time some of these polyps become colon cancers. Polyps may be small and produce few, if any, symptoms. Regular screening tests can help prevent colon cancer by identifying polyps before they become cancerous. If signs and symptoms of colon cancer do appear, they may include changes in bowel habits, blood in your stool, persistent cramping, gas or abdominal pain.
Many people with colon cancer experience no symptoms in the early stages of the disease. When symptoms appear, they’ll likely vary, depending on the cancer’s size and location in your large intestine. Signs and symptoms of colon cancer include: Continue reading About Colon cancer
Pancreatic cancer begins in the tissues of your pancreas — a large organ that lies horizontally behind the lower part of your stomach. Your pancreas secretes enzymes that aid digestion and hormones that help regulate the metabolism of sugars.
Pancreatic cancer often has a poor prognosis, even when diagnosed early. Pancreatic cancer typically spreads rapidly and is seldom detected in its early stages, which is a major reason why it’s a leading cause of cancer death. Signs and symptoms may not appear until pancreatic cancer is quite advanced and surgical removal isn’t possible.
Symptoms of pancreatic cancer
Signs and symptoms of pancreatic cancer often don’t occur until the disease is advanced. When signs and symptoms do appear, they may include: Continue reading Pancreatic cancer
Bladder cancer is a type of cancer that occurs in your bladder — a balloon-shaped organ in your pelvic area that stores urine. Bladder cancer begins most often in the cells that line the inside of the bladder. Bladder cancer typically affects older adults, though it can occur at any age.
The great majority of bladder cancers are diagnosed at an early stage — when bladder cancer is highly treatable. However, even early-stage bladder cancer is likely to recur. For this reason, bladder cancer survivors often undergo follow-up screening tests for years after treatment.
Bladder cancer signs and symptoms may include: Continue reading About Bladder cancer
Leukemia is cancer of your body’s blood-forming tissues, including your bone marrow and lymphatic system. It usually starts in your white blood cells.
Your white blood cells are potent infection fighters — they normally grow and divide in an orderly way, as your body needs them. But in leukemia, your bone marrow produces a large number of abnormal white blood cells, which don’t function properly. Leukemia isn’t just a children’s disease. It has four main types and many subtypes — and only some are common among children.
A diagnosis of leukemia can cause you a great deal of concern, and treatment can be complex — varying on the type of leukemia and other factors. But there are strategies and resources that may make your road easier.
Doctors classify leukemia in two ways.
Speed of progression
The first type of classification is by how fast the leukemia progresses: Continue reading About Leukemia – Causes, Diagnosis, Treatment
