20 Common Cancer Symptoms Almost Every Person Ignores
Cancer is a type of disease where cells grow out of control, divide and invade other tissues. In a person without cancer, cell division is under control. In most tissues, healthy cells divide in a controlled way and copy themselves to create new healthy cells.
With cancer, this normal process of cell division goes out of control. Cells change their nature because mutations have occurred in their genes. All the daughter cells of cancer cells are also cancerous.
If the abnormal cells do not invade, but just divide and swell up their original tissue, this is not called “cancer”.
It is called a tumour. Tumours are usually not a threat to life because they can be cut out. However, some tumours occur in places where they cannot be cut out, and they can be fatal. Some brain tumours are of this type.
The symptoms of cancer are caused by the cancerous cells invading other tissues.
This is called metastasis. Metastasis is a process in which cancer cells move through the bloodstream or lymphatic system. When this happens, a person’s cancer can be spread throughout his body. Eventually those other tissues cannot work as well, and the whole body begins to get worse, and may die.
Cancer can affect anybody at any age. Most types of cancer are more likely to affect people as they get older. This is because as a person’s DNA gets older, their DNA may become damaged, or damage that happened in the past may get worse. One type of cancer that is more common in young men, rather than older people, is testicular cancer (cancer of the testicles).
Cancer is one of the biggest and most researched causes of death in developed countries.
Cancer is one of the most common causes of death around the world. It causes about 12.5% (or one out of every eight) of all deaths worldwide, according to the World Health Organization.
Different types of cancer have different causes. Some things are known to cause cancer in a specific body part; other things are known to be able to cause many different types of cancer. For example, using tobacco (smoked or smokeless) can cause many types of cancers, such as lung, mouth, tongue, and throat cancers. Other things that are known to be able to cause cancer – or make a person more likely to get cancer – include: radiation including sunlight and X-rays in large or many doses, and exposure to radiation (for example in a nuclear power plant); chemicals and materials used in building and manufacturing (for example, asbestos and benzene); high-fat or low-fiber diets; air and water pollution; eating very little fruits and vegetables; obesity; not enough physical activity; drinking too much alcohol; and certain chemicals commonly used at home. Some cancers can also be caused by viruses. Many people who are exposed to these things do not get cancer – but some do.
Commonly Ignored Signs
Chest Pain or Chronic Cough
Bad cough and bronchitis are some of the symptoms of lung cancer and they are easy for detection. People who are affected by lung cancer experience chest pain that spreads towards the arm and their shoulders.
