Cancer: Simple tips on when to go to a doctor Cancer is believed to be the second most common cause of death after heart disease. Its symptoms can be similar to those of common diseases. For example, unexplained weight loss may be an indication of cancer. Typically, people ignore these early symptoms confusing them with other common conditions. Sometimes they are scared to consult a doctor. It is very important to detect cancer before it spreads, as treatment is most effective when cancer is found early. For example, if a breast lump is found at an early stage by self-examination, timely treatment can result in long cancer-free survival. Always remember that every symptom could be explained by a harmless condition. Still, it is important to be aware of the following symptoms of cancer and get them investigated. Unexplained loss of weight: Substances released by cancer cells can result in weight loss. This is non-specific and can also be the result of a prolonged infection. Still, an unexplained and unintended weight loss over a six-month period needs to be investigated. Fatigue: Patients with cancer experience ongoing tiredness. This could be caused by aneamia (low number of red blood cells in your body) due to an underlying disease like colon cancer, etc. Fatigue increases as cancer progresses. Pain:
Continuous pain that does not go away in a few months and keeps on getting worse may result from cancer. Bony pain may be a sign of cancer of the bone or a cancer that has started from a place like the prostate and has now travelled to the bone. A persistent cough or blood in the saliva:
This is especially relevant for long-term smokers, and is a common sign of lung cancer. Infectious diseases like tuberculosis can also present this way. Change in bowel habits or blood in the stool: Diarrhoea that does not go away, long-term constipation or change in the size of the stool (eg. Pencil thin stools) can signify colon cancer. Blood in the stools could be due to hemorrhoids, but even this needs to be investigated and treated by a doctor. Blood in the urine: Blood in the urine is typically due to kidney stones or a urinary infection. However, blood in the urine not accompanied by pain can be a sign of bladder cancer. Lump in any part of the body: Lumps in the breast may be non-cancerous, but still need to be evaluated thoroughly. Women are advised to conduct monthly breast examinations, especially if they have a family history of breast or ovarian cancer. Discharges from breasts are common, but if the discharge is bloody or only from one nipple, further evaluation is needed. Testicular cancer presents as a painless lump on the testicles. Many other cancers like those of the lymph nodes can present this way. Lumps most frequently are harmless and lymph nodes could be swollen due to an infection. A lump should be reported to your doctor if it is new and remains enlarged for more than a month or a previous lump that is rapidly growing in size. Changes in a mole or a wart: Any mole or wart that changes in size, shape, colour or if its edges get irregular may be cancerous. This should be reported to your regular doctor or a skin doctor immediately. Sores that do not heal: Sores normally heal quickly. If a sore fails to heal, it should be evaluated by a doctor. Non-healing mouth sores and persistent white or red patches in the mouth could be a sign of cancer. This is VERY IMPORTANT in patients who smoke or chew tobacco and should be evaluated as soon as possible. Though these symptoms are non-specific, if they meet the “2P” criterion (That is, if they are persistent and progressive), you should seek medical advice. Do not be afraid to visit your doctor as early detection may make all the difference. It is never too late to quit smoking, tobacco chewing and excessive alcohol intake. Remember, prevention is always better than cure. The writer is Chief Fellow, The Ohio State University Comprehensive Cancer Center Division of Hematology and Oncology, Ohio, USA. Email:

EYESIGHT Glaucoma is the second most common cause of blindness worldwide. It is estimated that 4.5 million persons globally are blind due to glaucoma, and that this number will rise to 11.2 million by 2020. Glaucoma refers to a group of eye conditions where the pressure within your eye is raised to such a degree that the optic nerve becomes damaged and you begin to lose your vision. The increase in pressure usually happens when fluid (the aqueous humor) in the front part of the eye (the anterior chamber) doesn’t drain away properly. Normally, the amount of fluid produced is balanced by the amount draining away; so the pressure in the front part of the eye stays constant. The two major types of glaucoma are chronic or primary open-angle glaucoma (POAG) and acute angle-closure glaucoma, with the angle referring to the configuration of internal eye structures that drain fluids. In angle-closure glaucoma, the fluid at the front of the eye, cannot reach the angle and leave the eye, and the patient can have severe pain due to sudden increase in eye pressure as well as redness of the eye, and blurred vision for which one needs to seek treatment immediately. In low-tension or normal-tension glaucoma, optic nerve damage and narrowed side vision occur in people with normal eye pressure. In congenital glaucoma children are born with a defect in the angle of the eye that slows the normal drainage of fluid and the children develop cloudy eyes, sensitivity to light, and excessive tearing. Conventional surgery typically is the safe and effective treatment, because medicines may have unknown effects in infants and may be difficult to administer. If surgery is done promptly these children usually have an excellent chance of having good vision. Secondary glaucoma can lead to other complications like advanced cataracts, eye injuries, eye tumors, or uveitis (eye inflammation). Corticosteroid drugs used to treat eye inflammations and other diseases can trigger glaucoma in some people. Treatment includes medicines, laser surgery or conventional surgery. Anyone can develop glaucoma. Some people are at higher risk than others. They include people over 40 years of age and those with a family history of glaucoma. Other potential risk factors include high myopia (very severe near-sightedness)/high hyperopia (near-sightedness), diabetes, eye surgery or injury, high blood pressure, use of steroids, etc. A comprehensive dilated eye examination can reveal more risk factors such as high eye pressure, thinness of the cornea, and abnormal optic nerve anatomy. In some people with certain combinations of these high-risk factors, medicines in the form of eyedrops reduce the risk of developing glaucoma by about half. As glaucoma remains untreated, people may miss objects to the side and out of the corner of their eye. Glaucoma can develop in one or both eyes. Glaucoma is detected through a comprehensive eye examination that includes visual acuity test. This eye chart test measures how well you see at various distances. A tonometer measures pressure inside the eye to detect glaucoma. Visual field test measures your side (peripheral) vision, loss of which is an early sign of glaucoma. In an effort to combat one of the main causes of blindness around the globe, the World Glaucoma Association and the World Glaucoma Patient Organisation have announced the first annual World Glaucoma Day, to be observed on March 6. Since glaucoma is a progressive disease causing irreversible visual loss, usually without warning until relatively advanced, and because 50 per cent of the affected people in the developed world (up to 90 per cent in developing countries) do not know that they have the disease and are, therefore, not only treatment but also community awareness needs to be significantly increased. This includes awareness of the disease and the need to have regular eye check-ups, thereby ensuring early detection of the problem and avoidance of what should be preventable visual disability.

Homoeopathy and You If you have frequent bloating in the abdomen, recurrent pain in your belly, and get loose stools or constipated very often, then there are good enough chances that you could be suffering from the irritable bowel syndrome (IBS). The IBS is a functional disorder of the intestines. It does not cause physical changes in your gut, but affects the functioning of the intestines. Though it is a functional disorder, it can seriously affect ones quality of life. Homoeopathy offers a very effective solution to deal with the IBS and can completely eradicate it from the body. So what exactly is the IBS and what causes it? The IBS is referred to as a condition when one or more of these symptoms are present in an individual. The main symptoms are abdominal pain or cramping, a bloated feeling, gas (flatulence) formation, diarrhoea or constipation (sometimes alternating with each other) and mucus in the stool. The symptoms can vary a great deal from individual to individual. Mostly the IBS affects individuals in a mild-to-moderate way, but in some patients, severity of symptoms can completely jeopardise their day-to-day life. For most of the people, the IBS (when untreated) is a chronic condition although it may vary in intensity from time to time. Although the cause of the IBS is not very clear, it is widely believed that the IBS is caused by disturbances in the nerve ending in the wall of the intestines, which control the muscles of the intestinal wall. Under normal circumstances, these muscles in the walls of the intestines contract and relax alternatively to push the digested food forwards the rectum (terminal part of the intestinal canal). These muscles work in a rhythmic and coordinated way. But in the case of those who have the IBS, these muscles start working in an erratic fashion. The muscles may suddenly start contracting in a very strong manner, casing the digested food to move out very speedily, leading to diarrhoea and cramps. On the other hand, if the contractions become slow the bowel movements become constipated. Bloating is thought to be caused by the heightened sensitivity of the intestinal wall. Even small amounts of gas can give a feeling of distension (“full of gas” feeling in the abdomen) due to the heightened sensitivity when intestinal walls are stretched even slightly by gas. People suffering from the IBS can have their symptoms triggered by external as well as internal factors. External factors are food substances like milk, alcohol, eggs and carbonated drinks. Stress is a major internal factor for triggering and affecting the symptoms of the IBS. Trigger factors can hugely vary from individual to individual. Homoeopathic medicines are very effective in managing and curing the IBS. They work by using the body’s own restorative abilities to counter the disease, thus giving a gentle and permanent cure. The treatment is best handled by a professional homoeopath as choosing the right medicine for the IBS can be a very challenging job. The medicines that have been found to be most effective in treating the IBS are Asafoetida, Colocynth, Argentum Nitricum, Nux Vomica, Lycopodium and Carbo
Vegetablis. The writer is a Chandigarh-based homoeopath.

Health Notes
A healthy individual loses about 100 strands of hair daily, with losses occurring evenly around the whole scalp. However, this hair is replaced. The problem begins when the shedding goes beyond that number, and replacement lags. Now, after six years of study, researchers at the University of Bonn have identified a gene that causes a rare hereditary form of hair loss — Hypotrichosis simplex — throwing open the possibility of regenerating hair. Protein that may help determine chemo effectiveness
LONDON: Researchers at Vanderbilt University Medical Centre have identified a protein that recognises tumours responding to chemotherapy. When tagged with a light-emitting molecule it can determine the efficacy of cancer treatments within days of its starting. The team of researchers led by Dennis Hallahan, the Ingram Professor of Cancer Research and chair of Radiation Oncology at Vanderbilt University Medical Centre, discovered that the protein that bound to tumours responding to therapy, when attached to a light-emitting molecule, could assess the treatment response in mice implanted with human tumours in just two days.

Viagra could damage
men’s fertility
MELBOURNE: Viagra might help men boost their performance in the bedroom, but it can also damage their ability to father a child, suggests a new British study. Researchers at the Queen’s University in Belfast have found that young men who take the anti-impotence drug recreationally could be damaging their sperm quality, thus spoiling their chances of starting a family.

LONDON: A study by researchers from Baylor College of Medicine in Houston has cited that a protein called Notch that manages the determination of cell differentiation into different kinds of tissues in embryos is crucial in the formation of bones and strength later in life. The results of this study may act as a base for understanding osteoporosis and also in diseases in which there is too much bone.
