Cancer Risk Factors
Though it's difficult to say why some people develop cancer while others don't, research shows that certain risk factors increase a person's odds of developing cancer. These risk factors include growing older, family history of cancer, diet, alcohol and tobacco use, and exposure to sunlight, ionizing radiation, certain chemicals, and some viruses and bacteria.
H. pylori (Helicobacter Pylori) Infection
Helicobacter pylori (H. pylori) is a bacteria that causes chronic inflammation (gastritis) of the inner lining of the stomach, and also is the most common cause of ulcers worldwide. About 50% of people in the world carries or is infected with H. pylori. Common symptoms of H. pylori infection are occasional abdominal discomfort, bloating, belching or burping, and nausea and vomiting. H. pylori infection is difficult to eradicate, and treatment is with two or more antibiotics.
Peptic Ulcer (Stomach Ulcer)
Peptic or stomach ulcers are ulcers are an ulcer in the lining of the stomach, duodenum, or esophagus. Ulcer formation is related to H. pylori bacteria in the stomach, use of anti-inflammatory medications, and cigarette smoking. Symptoms of peptic or stomach ulcers include abdominal burning or hunger pain, indigestion, and abdominal discomfort after meals. Treatment for stomach ulcers depends upon the cause.
Abdominal Pain (Causes, Remedies, Treatment)
Abdominal pain can have many causes that range from mild to severe. Some of these causes include bloating, gas, colitis, endometriosis, food poisoning, GERD, IBS (irritable bowel syndrome), ovarian cysts, abdominal adhesions, diverticulitis, Crohn's disease, ulcerative colitis, gallbladder disease, liver disease, and cancers. Signs and symptoms of the more serious causes include dehydration, bloody or black tarry stools, severe abdominal pain, pain with no urination or painful urination. Treatment for abdominal pain depends upon the cause.
Pernicious anemia is a blood disorder in which the body does not make enough red blood cells due to a lack of vitamin B12 in the blood. Pernicious anemia can develop from a lack of a protein that helps the body absorb vitamin B12, not getting enough B12 in the diet, and certain intestinal conditions that interfere with the absorption of vitamin B12 such as Crohn's disease, celiac sprue, or ulcerative colitis. There is no cure for pernicious anemia, thus treatment is life-long.
Anemia is the condition of having less than the normal number of red blood cells or less than the normal quantity of hemoglobin in the blood. The oxygen-carrying capacity of the blood is, therefore, decreased. There are several types of anemia such as iron deficiency anemia (the most common type), sickle cell anemia, vitamin B12 anemia, pernicious anemia, and aplastic anemia. Symptoms of anemia may include fatigue, malaise, hair loss, palpitations, menstruation, and medications. Treatment for anemia includes treating the underlying cause for the condition. Iron supplements, vitamin B12 injections, and certain medications may also be necessary.
Smoking (How to Quit Smoking)
Smoking is an addiction. More than 430,000 deaths occur each year in the U.S. from smoking related illnesses. Secondhand smoke or "passive smoke" also harm family members, coworkers, and others around smokers. There are a number of techniques available to assist people who want to quit smoking.
Cancer is a disease caused by an abnormal growth of cells, also called malignancy. It is a group of 100 different diseases, and is not contagious. Cancer can be treated through chemotherapy, a treatment of drugs that destroy cancer cells.
Certain behavioral, lifestyle, and environmental factors contribute to cancer. Cancer prevention involves modifying these factors to decrease cancer risk. Tobacco use, alcohol consumption, physical inactivity, inadequate fruit and vegetable intake, and obesity increase the risk of certain cancers. Vaccines, genetic testing, and cancer screening also play a role in cancer prevention.
Radon (A Citizen's Guide to Radon)
Radon is a radioactive gas that has been confirmed to cause cancers. About 21,000 individuals die each year due to radon exposure. Radon can be found in the ground, water supply, and the air you breathe. It is found in schools, homes, offices, and other buildings. You can purchase a Radon Test Kit and have the sample sent to the state radon office. Research has shown that the risk of lung cancer from breathing radon in air is much greater than the risk of stomach cancer from swallowing water with radon in it. The EPA offers a Consumers Guide to Radon Reduction so you can take action to reduce radon levels in your home, school, or office. Scientists are more certain about radon risks than from most other cancer-causing substances.
The Digestion Process (Parts, Organs, and Functions)
Digestion is the complex process of turning the food you eat into the energy you need to survive. The digestive process also involves creating waste to be eliminated, and is made of a series of muscles that coordinate the movement of food. Learn more about digestion and the body parts that make it possible, including the mouth, pharynx, esophagus, stomach, small intestine, colon, rectum, anus, pancreas, liver, and gallbladder.
Nausea and Vomiting (Causes, Natural Remedies, Diet, Medication)
Nausea is an uneasiness of the stomach that often precedes vomiting. Nausea and vomiting are not diseases, but they are symptoms of many conditions. There are numerous cases of nausea and vomiting. Some causes may not require medical treatment, for example, motion sickness, and other causes may require medical treatment by a doctor, for example, heart attack, lung infections, bronchitis, and pneumonia. Some causes of nausea and vomiting may be life threatening, for example, heart attack, abdominal obstruction, and cancers. Treatment of nausea and vomiting depends upon the cause.
Cancer fatigue is a lack of energy that is caused by cancer or cancer treatment, including chemotherapy, radiation, biological therapy, or bone marrow transplantation. Strategies to combat cancer fatigue include scheduling rest, pacing oneself, planning ahead and prioritizing work and activities, eating the right foods, exercising, and practicing proper body mechanics.
Symptoms of 12 Serious Diseases and Health Problems
Learn how to recognize early warning signs and symptoms of serious diseases and health problems, for example, chronic cough, headache, chest pain, nausea, stool color or consistency changes, heartburn, skin moles, anxiety, nightmares, suicidal thoughts, hallucinations, delusions, lightheadedness, night sweats, eye problems, confusion, depression, severe pelvic or abdominal pain, unusual vaginal discharge, and nipple changes. The symptoms and signs of serious health problems can be caused by strokes, heart attacks, cancers, reproductive problems in females (for example, cancers, fibroids, endometriosis, ovarian cysts, and sexually transmitted diseases or STDs), breast problems (for example, breast cancer and non-cancer related diseases), lung diseases (for example, chronic obstructive pulmonary disease or COPD, lung cancer, emphysema, and asthma), stomach or digestive diseases (for example, cancers, gallbladder, liver, and pancreatic diseases, ulcerative colitis, or Crohn's disease), bladder problems (for example, urinary incontinence, and kidney infections), skin cancer, muscle and joint problems, emotional problems or mental illness (for example, postpartum depression, major depression, post-traumatic stress disorder (PTSD), mania, and schizophrenia), and headache disorders (for example, migraines, or "the worst headache of your life), and eating disorders and weight problems (for example, anorexia or bulimia).
Gastritis Symptoms, Causes, Diet, Home Remedies, Treatment, and Cure
Gastritis (acute and chronic) is an inflammation of the lining of the stomach Some people have no gastritis symptoms, but when they do occur they may include bloating, belching, loss of appetite, nausea, and vomiting. H. pylori infection and nonsteroidal anti-inflammatory drugs (NSAIDs) are the two main causes of gastritis. Alcohol, caffeine, and high-fat foods also can cause gastritis. Fried, fatty, and spicy foods, and alcohol aggravate gastritis symptoms. Other stomach lining irritants that aggravate symptoms include cigarette smoking, acidic juices, caffeine, tomato products, peppers, and chili powder. Foods that sooth gastritis symptoms, and that help reduce and stop H. pylori infection growth in the stomach include apples, onions, garlic, teas, green leafy vegetables, coconut water, and wheat bran. Gastritis is diagnosed with endoscopy, blood tests, or stool tests. Some people get relief from gastritis symptoms with prescription and non-prescription antacids, histamine blockers like famotidine (Pepcid AC) or ranitidine (Zantac 75), or proton pump inhibitors (PPIs) like omeprazole (Prilosec) and esomeprazole (Nexium). These drugs will not cure gastritis. Complications of gastritis include gastric cancers, MALT lymphoma, renal problems, and death.
Swollen Lymph Nodes (Glands)
Lymph nodes help the body's immune system fight infections. Causes of swollen lymph nodes (glands) may include infection (viral, bacterial, fungal, parasites). Symptoms of swollen lymph nodes vary greatly, but may include fever, night sweats, toothache, sore throat, or weight loss. Causes of swollen lymph nodes also vary, but may include cancer, the common cold, mono, chickenox, HIV, and herpes. The treatment of swollen lymph nodes depends upon the cause.
Ascites, the accumulation of fluid in the abdominal cavity is most commonly caused by cirrhosis of the liver. Some of the other causes of ascites include portal hypertension, congestive heart failure, blood clots, and pancreatitis. The most common symptoms include increased abdominal girth and size, abdominal bloating, and abdominal pain. Treatment depends on the cause of ascites.
Tumor grade is a system used to classify cancer cells in how likely the tumor is to grow and how abnormal they look under a microscope. Tumor grade is not the same as tumor stage. A biopsy is taken to determine if the tumor is benign (non cancerous) or malignant (cancerous).
Why Am I So Bloated and Gassy?
Bloating is a feeling that your abdomen is distended or larger than normal, but it does not necessarily mean that it is. Gas (flatulence) also can be a problem if you are bloated. Common, less serious causes of bloating are eating too fast, too much, or too many fatty foods; swallowing air; pregnancy; and menstruation. Cancer and IBD (ulcerative colitis and Crohn's disease) are examples the more serious causes of bloating. Examples of foods and drinks that cause bloating are high fiber foods if you don't eat them regularly; eventually the bloating and gassiness will resolve if you eat them on a regular basis; fatty greasy foods, dairy products (for example, cheese, ice cream, milk, and yogurt); foods high in salt (for example, processed, frozen, and canned foods), and artificial sweeteners. Some doctors and other health care professionals recommend natural remedies like chamomile or peppermint tea, or pumpkin to relieve bloating. Examples of OTC medicine (medicine available without a prescription) and other products that may relieve bloating and gassiness are, Gas-X, Beano, Pepto Bismol, Metamucil, probiotics, and Ex-Lax for constipation associated with bloating. If you have persistent or severe gas and bloating, and if you have any of these symptoms see a doctor or other healthcare professional, shortness of breath, heart palpitations, chest pain, bloody diarrhea, fever, or if you think you are or may be pregnant.
