Answer:
A tumor refers to a lump or mass of tissue, which may look like an inflammation. However, not all tumors are cancerous. The development of a tumor takes place when the proliferation of cells takes place too briskly.
The size of a tumor can vary in size, that is, from a large mass to a tiny nodule, on the basis of the type, and it can appear almost anywhere on the body. There are primarily two type of tumor known. These are benign, that is, non-cancerous and malignant, that is, cancerous.
In the given case, the patient possessing a tumor in the vertebral cavity or the canal would likely develop symptoms first. This is due to the fact that vertebral cavity exhibits less space in comparison to the abdominopelvic cavity. Therefore, the tumor would interfere with the muscles, nerves, and other parts of the body before the abdominopelvic tumor would develop large enough to disturb the organs present in that cavity.
