1. Digestive problems: manifested as nausea, vomiting, indigestion, upset stomach, bloating, diarrhea, etc. You may have no appetite at all during the treatment process. Even if you don’t feel hungry, it is important to consume more protein and calories. Doctors found that patients with good appetite can better deal with cancer and its side effects. 2. Blood reaction: It can be manifested as bone marrow suppression such as lowering of white blood cell count in peripheral blood and platelet reduction. If the above situation occurs treatment will be suspended for a week in order to increase the patient’s blood cell count. However, radiotherapy for liver cancer will hardly reduce the number of white blood cells or platelets, which help the body resist infection and prevent bleeding. 3. General fatigue: During radiotherapy, the body uses a lot of energy to heal itself. The stress caused by the disease, the daily commute to treatment and the effect of radiation on normal cells can all lead to fatigue. Most liver cancer patients will feel tired after several weeks of radiotherapy, and they will feel more fatigued as the radiotherapy continues. 4. Skin reaction: Radiation reaction of the irradiated skin is generally divided into three degrees; the first degree radiation skin reaction is dry dermatitis, with erythema, itching, hair loss, hyperpigmentation, follicle expansion and acne-like changes in the irradiated skin. Second degree radiation skin reaction is moist dermatitis, the skin is congested and edematous, transparent blisters of different sizes appear, which can exude fluid after rupture, and the self-conscious burning pain is severe. Third degree of skin radiation reaction is radioactive ulcer and tie up, feel painful, ulcer is difficult to heal, often need to remove skin implant. The skin radiation damage varies according to the irradiation site, radiation quality, irradiation dose and irradiation range, and there are great differences among individuals.
