What is cancer symptoms ?

Initially, the cancer is small mass of cells, which do not produce any symptoms. As the growth of cancer, physical appearance can affect surrounding tissue. Also, some cancers, release certain substances or trigger immune reactions that cause symptoms in other parts of the body that are not close to the cancer (paraneoplastic syndrome).

Cancer affects nearby tissues by growing into or pushing the surrounding tissue, thereby irritating or pressing them. Irritation typically causes pain. Pressure can inhibit the network to perform their normal functions. For example, bladder cancer or cancer of the lymph nodes in the abdomen can suppress the tubes (ureters) that connect the kidneys to the bladder blocking the flow of urine.

Lung cancer may block the flow of air through the lungs, causing lung collapse and facilitate infection. In any cancer can suppress blood vessel, closing the bloodstream and cause bleeding. When cancer develops in areas with lots of space, as in the colon wall, it can not cause any symptoms until it becomes very large. In contrast, cancer develops in a more narrow space, such as the vocal cords can cause symptoms (such as raspy) when the cancer is still relatively small.

If a cancer spreads (metastasizes) to other body parts, the same local effect on the irritation and pressure occurs rapidly, but in a new location, these symptoms may be quite different. Cancers associated with the membrane that protects the lungs (pleura) or bag-like structure that surrounds the heart (pericardium) often secrete fluid, which accumulates around the organs, the buildup of fluids in large amounts can interfere with breathing or heart pumping.

Painful

Cancer is usually not painful at first. With the development of their first symptoms are often mild discomfort, which can be very severe pain can be increased as the enlargement of cancer. The pain can occur from pressure or landslides cancer into nerves or other structures. Nevertheless, not all cancers cause severe pain. By the same token, lack of pain does not guarantee that the cancer does not develop or spread.


Bleeding

Initially, the cancer can be a little bleeding from his cell does not stick well to each other and fragile blood vessels. Then, as the enlargement of the cancer and attack the tissues around, this could develop into a blood vessel in the vicinity, causing bleeding. The bleeding is probably lighter and not be detected or be detected only by testing. As is often the case in the first stage of colon cancer. Or, especially with advanced cancer, bleeding may be more significant, even major and life threatening.

The location of the cancer to make sure the location of the bleeding. Cancer anywhere along the gastrointestinal tract can cause bleeding in the stool. Cancer anywhere along the urinary tract can cause bleeding in the urine. Other cancers can bleed into the inside of the body. Bleeding into the lungs can cause the person to cough up blood.


Weight Loss and Fatigue

Generally, a person with cancer may experience weight loss and fatigue, which could get worse as the cancer advances. Some people claim to lose weight despite good appetite. Others lose their appetite and even nausea by food or have difficulty swallowing. They can be thin; loss of underlying fat, especially visible on the face. People with advanced cancer are often very tired and slept many hours a day. If anemia is formed, this person could find that they feel tired or become short of breath with even mild activity.


Swollen Lymph Nodes

As represented in the cancer began to spread around the body, it was the first time can spread to nearby lymph nodes, become swollen. Swollen lymph nodes that may not be painful or light, and feels hard and rubbery. They were easily removed, or, if the cancer is more advanced they can jam on the overlying skin, to the deeper layers in the network below, or both.


Depression

Cancer often results in depression. Depression can be associated with symptoms of pain, fear of dying, or loss of freedom. In addition, some cancers can produce substances that directly cause depression by affecting the brain.


Neurological symptoms and muscular

Cancer can develop into natural or compress nerves, causing some of the symptoms of nerve and muscle diseases, including changes in sensation (such as tingling) or weakness of muscles. When cancer develops in the brain, symptoms may show symptoms appropriately, firmly but can include headache, dizziness, headache, nausea, changes in vision, and seizures. Neurological symptoms can also be part of Paraneoplastic Syndrome.


Respiratory symptoms

Cancer can suppress or block structures, such as the airways in the lungs, causing difficulty breathing, coughing, or pneumonia. Breathing difficulties can also occur when the cancer causing huge plural effusion, hemorrhage into Kriya lungs, or anemia.
