Initially, the cancer is a small mass of cells, which do not produce any symptoms. As the growth of cancer, physical appearance can affect the surrounding tissue. Also, some cancers, issued a certain substance or trigger an immune reaction that causes symptoms in other parts of the body that are not close to the cancer (paraneoplastic syndrome).
Cancer affecting the surrounding tissue with growth or push into surrounding tissue, thereby irritating or pressing them. Irritation typically causes pain. Pressure can prevent the network to perform their normal functions. For example, bladder cancer or cancer in the abdominal lymph nodes can suppress vessel (ureter) that connects the kidney to the bladder urine flow clogging.
Lung cancer can clog the flow of air through the lungs, causing lung collapse and facilitate infection. In any cancer can suppress the blood vessels, closing the blood flow and cause bleeding. When cancer develops in areas with lots of space, such as the colon wall, it can not cause any symptoms until it becomes very large. Conversely, the cancer develops in a more narrow space, such as the vocal cords can cause symptoms (such as harsh) when the cancer is still relatively small.
If the cancer spreads (metastasizes) to other body parts, the same local effect on the irritation and pressure occurs rapidly, but at the new location, these symptoms are likely very different. Cancers associated with the membrane that protects the lungs (pleura), or structures such as the bag that surrounds the heart (pericardium) are often issued a liquid, which accumulates around the organs, the accumulation of large amounts of fluid can interfere with breathing or heart pumping.
Pain
Cancer is usually not painful at first. With their development, the first symptom is often a sense of mild discomfort, which can be can be a severe pain increased as the enlargement of cancer. The pain can occur from pressure or erosion cancer into nerves or other structures. Nevertheless, not all cancer causing severe pain. In the same way, the lack of pain does not guarantee that the cancer does not grow or spread.
Bleeding
Initially, the cancer can be a little bleeding because the cell does not stick well to each other and fragile blood vessels. Then, as the enlargement of the cancer and attack the tissues around, it can develop into blood vessels nearby, causing bleeding. Bleeding is likely to be mild and not detected or can be detected only by tests. As is often the case in the first stage of colon cancer. Or, especially with advanced stage cancer, the possibility of more significant bleeding, even large and life-threatening.
Location of cancer to ensure 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 parts of the body. Bleeding into the lungs can cause the person is coughing up blood.
Losing Weight and Fatigue
Generally, a person suffering from cancer may experience weight loss and fatigue, which could get worse as the cancer advances. Some people claim to lose weight despite good appetite. The others lost their appetite and can even dimualkan 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 for hours a day. If anemia is formed, this person could find that they feel tired or become difficult to breathe even with light activity.
Swollen lymph node
Sebagaiman cancer began to spread around the body, the first time it may spread to surrounding lymph nodes, become swollen. Swollen nodes painful or may not light, and feels hard and rubbery. They were easily removed, or, if their cancer can be further involved in the overlying skin, to the deeper layers of tissue below, or both.
Depression
Cancer often meghasilkan Depression. Depression can be associated with symptoms of pain, fear of dying, or loss of freedom. In addition, some cancers may produce substances that directly cause depression by affecting the brain.
Neurological symptoms and muscular
Cancer can grow to a natural or pressing the nerve, causing some symptoms of nerve and muscle disease, including changes in sensation (such as amusement) or muscular weakness. When cancer develops in the brain, symptoms may show symptoms appropriately, firmly but can include headache, dizziness, headache, nausea, changes in vision, and attack. Neurological symptoms may also be part of the Paraneoplastic Syndrome.
Respiratory symptoms
Cancer can suppress or block structures, such as the airways in the lungs, causing difficulty breathing, coughing, or pneumonia. Difficulty breathing can also occur when the cancer causing huge plural effusion, bleeding into the lungs dalan, or anemia.
