After nail cancer surgery, it is necessary to pay attention to wound care, pay attention to reasonable diet, and do activities appropriately. 1. Wound care: after nail cancer surgery, pressure bandage with chest strap is needed. If the compression is too tight, it may lead to blood flow obstruction and skin flap of the upper limb on the operation side. If the bandage is loose, it will be easy to accumulate fluid under the skin flap, which is unfavorable to the healing of incision. 2. Pay attention to reasonable diet: after surgery, patients can eat more vegetables and fruits or choose mixed grains, coarse grains, crude fiber and other foods. Avoid alcohol and tobacco, and limit the intake of high fat, pay attention to oil control and salt restriction. 3. Appropriate activities: after the operation of nail cancer, patients should pay attention to let them go underground for some walks appropriately. Because if they do not move for a long time, it may cause deep vein embolism of lower limbs. After the operation of nail cancer, patients need to go to hospital for rechecking regularly and observe the changes of their body, and should consult doctor in time if they feel uncomfortable.
