Somatization in cancer.

Somatic symptoms can occur in disease-free cancer patients. The causes of such symptoms in cancer can be many and varied. These could be due to anxiety, depression, somatization or a manifestation of illness behaviour. Somatic symptoms can also arise out of treatments for the cancer like radiation treatment or chemotherapy. Cancer related somatic symptoms have cognitive, psychological, and physiological causes, each of which is amenable to treatment. The occurrence of somatoform disorders in cancer patients is likely to complicate the treatment and outcome of the cancer. Common somatic symptoms in cancer have been found to be pain, fatigue, anorexia, tiredness or exhaustion, weakness, reduced energy, lethargy, and tremors. Breathlessness, muscle pain, dizziness, and palpitation are common symptoms of anxiety and panic attack which have also been noted in cancer patients. Somatic concern and preoccupation are also common. These symptoms create difficulty in diagnosing depression and anxiety in cancer patients, and leads to the need for modification of the standard diagnostic criteria. Somatic symptoms in cancer respond to counselling and psychopharmacotherapy. More research are needed on this area to understand the process of somatization in a somatic disease.
