Patients with numbness in the back may not necessarily be caused by cancer, but in most cases, other causes of numbness in the back should be considered, that is, the possibility of numbness in the back caused by cancer is minimal. The first consideration for numbness in the back is caused by muscle strain or cold stimulation in the lumbar region, as well as prolonged compression. Of course, spinal diseases should also be highly noted to cause numbness in the back, such as osteophytes in the thoracic and lumbar spine, inflammation and strain in the soft tissue of the lumbar spine. Patients with numbness in the back should also pay attention to the presence of lumbar muscle strain, which may also lead to discomfort in the back, in most cases, accompanied by pain in the back, especially in the morning after waking up, the discomfort in the back is more obvious. Of course, cancer is also a possibility, but it is impossible to determine the cause of cancer just by the numbness in the back of the patient. Therefore, timely examination should be conducted when necessary to determine the cause of the numbness in the back and to rule out cancer. Therefore, if necessary, an MRI of the back and, if necessary, a pathological examination should be performed to determine whether it is cancer. Pay attention to the protection of the lower back. Do not bend your back too often.
