The pain site of early stage bone cancer is generally related to the severity of the disease and the location of the lesion, which needs to be analyzed on a case-by-case basis. The pain of early bone cancer is generally mild, and patients may only show mild vague pain or even may have no pain. However, with the development of the disease, local pain and discomfort may appear. Generally, bone cancer pain often occurs at the lesion site. If it is a lesion of lower limbs, it may lead to pain and swelling of lower limbs; if it is a lesion of lumbar spine, it may lead to pain of lower back and weakness of movement, etc., and even affect work and life. As the disease progresses again, patients may also develop severe osteoporosis, which may lead to pathological fracture. Therefore, patients should avoid strenuous activities in daily life, prevent bumps and bruises, and pay attention to a high-calorie, high-protein, vitamin-rich and easy-to-digest diet to improve the body’s ability to resist disease.
