The word cancer could be the last thing that any one wants to hear. The cancer is caused when there is any abnormal growth of the cells in a specific part of the body. When this happens in the bone tissues, it is called the bone cancer. There are three kinds of bone tissues in the bone – Compact tissue which is the hard outside of the bone. Cancellous tissue is on the inside which makes blood cells and the Subchondral tissue which are the tissues of the joints. The abnormal cell growth can happen in any of these tissues causing bone cancer. Benign or noncancerous; Malignant or cancerous; primary bone cancer and the secondary bone cancer are the various kinds of bone cancer.

The bone cancer causes are not quite clear despite the development of the medical sciences. The doctors can’t really explain that why some one has bone cancer and the other person doesn’t. Though, they can say for sure that bone cancer is not contagious. The doctors can’t explain why, but they believe that if a person is exposed to certain risk factors, he could have or can develop bone cancer. The risk factors would include – being at a certain age, being a young adult or a child; previous chemotherapy or radiation; Paget’s disease history; any history of bone cancer in the family; inheritance of retinoblastoma.

The symptoms of bone cancer could be a little tricky. An even a slight sign that could possibly indicate that one has bone cancer should rush to the doctor without delay. The patient might experience bone pain; tenderness & swelling near the affected area would be surfaced; the bones would go weak and would be quite prone to fracturing; unintended weight loss would be noticed and the person would start feeling weak. Fever and anemia could be other signs of bone cancer as well.

The treatment of bone cancer would depend upon many factors – like the stage at which the patient is, can the same be treated by drugs, how severe the symptoms are. Surgery could be an option where the part affected is removed. The surgery for bone cancer would include one for removal of the entire limb, when the cancer is in a complicated area or is covering a large area for that matter. Surgery to remove the affected area only and not the limb could be the second type of surgery and then the surgery which would not affect the limbs. Chemotherapy and Radiation therapy are the other alternative treatments for bone cancer.

The patient should be aware of all the possible treatments in details, so that he would be able to make a prudent decision about the same. The family should take care that the patient is not too depressed because of the situation, meeting other people with cancer, could help coping up with the cancer. A positive outlook is really important for any treatment to work. One needs to take all the precautions and treatment as directed by the doctor.

Gums are an anchor of our teeth. Just as roots hold trees firmly to the ground, it is our gums which fix the teeth to the jaw. Keeping gums healthy is very important and this governs the overall oral health. In fact, it is as important to look after gums as it is to look after teeth. Surveys reveal that more people are falling easy prey to gum diseases. The matter of concern is that gum diseases are no longer restricted only to the aged. Even young people and generally teenagers develop this condition.

Early detection of symptoms helps in quick recovery of the problem. The symptoms of these diseases are sometimes very evident, but not always. This is where medical intervention may be needed.

The onset of gum disease:

The condition actually begins with the deposition of plaque (a slimy substance) around the teeth. This is a transparent layer and hence sometimes goes un-noticed. Plaque is the media where the harmful bacteria thrive and form colonies. These bacteria produce acids which not only damage the tooth enamel but also affect the gums.

Gingivitis and Periodontitis:

Gingivitis is a condition of the gums which is not so easy to detect and only an expert can make a proper judgment. The symptoms of gingivitis are sometimes very mild, though in the long run it can prove harmful. Spongy gums, bleeding gums or even mild swelling of gums can be the beginning of this condition. The condition is worsened with plaque deposits that continuously damage the gums.

Periodontitis is a more serious condition as compared to gingivitis. It not only affects the gums but also the jaw bones. The condition needs quick medical attention and if not treated early can pose more serious problems. Periodontitis causes the gums to bleed and in extreme cases the gums lose the hold on teeth completely. The result is an irreversible loss of teeth. The other symptoms include difficulty in biting and chewing food. This symptom cannot be traced until an expert or a oral surgeon gives an opinion. Special techniques are used by experts to find out if the bite has the proper force or not.

Another problem which is common in most of the gum infections is the exposed roots of teeth. These roots are normally protected under the gum layer. However when the gums are affected, they tend to shrinkFree Articles, exposing these roots. This leads to increased sensitivity to extreme temperatures and difficulty in eating as well.

Nervous Breakdown is also well known as mental breakdown. There are several causes which contribute to the problem of nervous breakdown. But social isolation is regarded as one of the major causes of nervous breakdown. There may be several reasons behind social isolation. It hardly matters, as the damage caused by this factor is quite irreparable.

The following are the general signs and symptoms of a nervous breakdown. A person might experience some of them simultaneously or only one of them in an exaggerated form. The type of symptoms occurring varies from individual to individual depending upon their mental stability and past history of mental disorders.

Symptoms of Nervous Breakdown

1. Physically - A brain with excessive stress is the first indicator of a nervous breakdown. Feelings of lethargy, constant pains and aches, scratchy and inflamed skin, lowered body resistance are also signs of an imminent breakdown. Repeated sensations of vomiting and gastric problems like stomach cramps gastrointestinal ulcers, colitis and diarrhea over extended periods of time might be indicative of a nervous breakdown.

2. Hostile Behavior – This involves a person displaying excessive antisocial behavior like gambling, eve teasing, vandalism and alcoholism. In extreme cases a person might resort to overt usage of drugs which is quite a clear sign of nervous breakdowns although it is not a rule.

3. Amnesia - Constantly forgetting appointments and schedules, short term memory lapse, confusion over order of occurrence of past events describe amnesia which, left untreated may lead to frustration. Frustration may then take control over the sufferer leading to rage and outbursts.

4. Delirium - Individuals may show signs of delirium and visualize hallucinations and delusions. By hallucinations and delusions one means tasting, smelling, seeing, feeling and hearing things that do not exist in reality. They might also display narcissism which is a state of extreme self-adoration and vanity.

People on the verge of a nervous breakdown are known to have nightmares and become obsessed with terrors. Panic attacks, loss of self-esteem, sleepwalking, and morbid thought patterns are symptoms of nervous wrecks as well. Such people may also threaten to harm and destroy other people, or hurt oneself by committing suicide.

Overview
