Do all tumors show up on ultrasound?

A special type of imaging test, an ultrasound produces information that can be helpful for diagnosing cancer, particularly in soft tissues. Oftentimes, it is used as the first step in the standard cancer diagnostic process. Ultrasound offers many benefits; for instance, a test can be performed relatively quickly and cost effectively without exposing the patient to radiation. However, ultrasound does not produce images with the same level of clarity or detail as a CT or MRI scan, nor can it confirm a cancer diagnosis on its own.

Traditional ultrasound testing

During a traditional ultrasound test, a medical professional slowly glides a specialized device (transducer) over the patient’s skin in the area of the body being studied. The transducer produces a series of high-frequency sound waves that "bounce off" the patient’s internal organs. The resulting echoes return to the ultrasound machine, which then converts the sound waves into two-dimensional images (sonograms) that can be viewed in real time on a monitor.

Endoscopic ultrasound testing

An ultrasound test can also be performed endoscopically. During this minimally invasive imaging procedure, a medical professional inserts an endoscope (a long, flexible, lighted tube with an attached transducer) into the patient’s mouth or rectum, rather than passing the transducer over his or her skin.

How ultrasound can contribute to a cancer diagnosis

The shape and intensity of ultrasound echoes can vary depending on the density of the tissue being evaluated. Because sound waves echo differently from fluid-filled cysts and solid masses, an ultrasound can reveal tumors that may be cancerous. However, further testing will be necessary before a cancer diagnosis can be confirmed. At Moffitt Cancer Center, our ultrasound services are provided by certified and experienced technicians, and the results are analyzed by a team of board-certified radiologists.

healthline.com - Itchy Skin as a Cancer Warning Sign - Healthline

Itchy skin , medically known as pruritus, is a sensation of irritation and discomfort that makes you want to scratch. Itching can be a symptom of certain types of cancer . Itching can also be a reaction to certain cancer treatments. A 2018 study of over 16,000 people in the Johns Hopkins Health System indicated that patients with generalized itching were more likely to have cancer than patients who didn’t notice itch. The types of cancers that were most commonly associated with itching included:

Skin cancer

Typically, skin cancer is identified by a new or changing spot on the skin. In some cases, itchiness might be the reason that the spot was noticed.

Pancreatic cancer

Those with pancreatic cancer may experience itching. The itch, however, isn’t a direct symptom of the cancer. Jaundice may develop as the result of a tumor blocking the bile duct and chemicals in the bile can enter the skin and cause itching.

Lymphoma

Itching is a common symptom of skin lymphoma, T-cell lymphoma, and Hodgkin’s lymphoma. Itching is less common in most types of non-Hodgkin’s lymphoma. The itching might be caused by chemicals released by the immune system in reaction to the lymphoma cells.

Polycythemia vera

In polycythemia vera, one of the slow-growing blood cancers in a group known as myeloproliferative neoplasms, itchiness may be a symptom. The itching might be especially noticeable after a hot shower or bath.
