What does enlarged lymph nodes indicate?

Lymph nodes are part of the lymphatic system which is also our 'defense' system. They serve to trap germs that may be circulating in our body. They drain lymphatic fluid from organs near where the nodes are located. For example, any disease in the head and neck areas may cause enlargement of nodes in the neck. They also may trap cancer cells if present in any particular part of the body. Both infectious and cancerous processes can cause enlargement of the node, which may be rapid or gradual. The enlarged nodes may or may not cause pain. It does not automatically mean that cancer is present.

Which tumor markers are considered to be reliable indicators for cancer?

Tumor markers are in short, not reliable indicators for cancer. They are proteins produced by cancer cells and normal cells. Therefore they are always measurable in someone's blood tests and will never have a zero value. They are, however, included in most health screening packages, and therefore helpful when interpreted in conjunction with other parameters, as well as the patient's signs and symptoms. This will help guide subsequent investigations towards a particular organ system should the related tumor marker appear elevated.

How do surgeons determine if a cyst is benign or malignant and requires removal?

Most cysts are actually benign. Malignant cysts refer to cysts that harbour cancer or those with a potential to develop into cancer. In determining whether or not they are malignant, the cysts are monitored for changes in size and consistency with regular ultrasounds. In some cases, you might also need to get an MRI. The surgeon would choose the necessary treatment based on symptoms such as: Pain Enlargement of the cyst size Presence of solid tissue within the cyst Treatment does not necesarry mean removal.
