How is Hodgkin's disease diagnosed?

I'm trying to learn all about Hodgkin's disease. How is it diagnosed. Please tell me some anwers, thank you!

Hodgkin's disease is one of a group of cancers called lymphomas.
Symptoms of Hodgkin's disease

Symptoms of Hodgkin's disease may include the following:

A painless swelling in the lymph nodes in the neck, underarm, or groin
Unexplained recurrent fevers
Night sweats
Unexplained weight loss
Itchy skin
When symptoms like these occur, they are not sure signs of Hodgkin's disease. In most cases, they are actually caused by other, less serious conditions, such as the flu. When symptoms like these persist, however, it is important to see a doctor so that any illness can be diagnosed and treated. Only a doctor can make a diagnosis of Hodgkin's disease. Do not wait to feel pain; early Hodgkin's disease may not cause pain.

Diagnosis and staging of Hodgkin's disease

If Hodgkin's disease is suspected, the doctor asks about the person's medical history and performs a physical exam to check general signs of health. The exam includes feeling to see if the lymph nodes in the neck, underarm, or groin are enlarged. The doctor may order blood tests.

The doctor may also order tests that produce pictures of the inside of the body. These may include:

X-rays: High-energy radiation used to take pictures of areas inside the body, such as the chest, bones, liver, and spleen.
CT (or CAT) scan: A series of detailed pictures of areas inside the body. The pictures are created by a computer linked to an x-ray machine.
MRI (magnetic resonance imaging): Detailed pictures of areas inside the body produced with a powerful magnet linked to a computer.
The diagnosis depends on a biopsy. A surgeon removes a sample of lymphatic tissue (part or all of a lymph node) so that a pathologist can examine it under a microscope to check for cancer cells. Other tissues may be sampled as well. The pathologist studies the tissue and checks for Reed-Sternberg cells, large abnormal cells that are usually found with Hodgkin's disease.
