Patients with brain cancer would start experiencing fatigue sooner or later. Not all brain tumors are brain cancer, but when they are one of the most common manifestations is weight loss, fatigue, lethargy, and loss of appetite. This is a wasting syndrome found in brain cancer as well as many other severe health problems. Different from feeling tired, people with cancer are exhausted, and their drowsiness is not often improved after a good night’s rest.
The tumor is taking a lot of the energy required for living and moving, and increasing their energy consumption exponentially, and that’s why they start having energy problems. Even making their bed might become a challenge, and they have difficulty concentrating as well.
