Pain in cancer can be produced by mechanical (e.g. pinching) or chemical (e.g. inflammation) stimulation of specialized pain-signalling nerve endings found in most parts of the body (called nociceptive pain), or it may be caused by diseased, damaged or compressed nerves, in which case it is called neuropathic pain.
The diagnostic workup for OGJ adenocarcinoma usually involves performing an endoscopy with endoscopic biopsy of suspicious looking tissue. Accurate staging of tumor extent and involvement of surrounding tissue or distant metastases is critical to establishing a prognosis, and is usually guided by endoscopic ultrasound, computed tomography scans, and/or positron emission tomography scans to ...
Esophageal cancer is cancer arising from the esophagus—the food pipe that runs between the throat and the stomach. [2] Symptoms often include difficulty in swallowing and weight loss. [ 1 ] Other symptoms may include pain when swallowing , a hoarse voice , enlarged lymph nodes ("glands") around the collarbone , a dry cough, and possibly ...
Bone pain belongs to the class of deep somatic pain, often experienced as a dull pain that cannot be localized accurately by the patient. This is in contrast with the pain which is mediated by superficial receptors in, e.g., the skin. Bone pain can have several possible causes ranging from extensive physical stress to serious diseases such as ...
Early pancreatic cancer does not tend to result in any symptoms, but when a tumor is advanced, a patient may experience severe pain in the upper abdomen, possibly radiating to the back. [8] Another symptom might be jaundice, a yellowing of the skin and eyes. [9] Pancreatic cancer has a poor prognosis, [2] with a five-year survival rate of
Some people also experience a sensation known as globus esophagus, where it feels as if a ball is lodged in the lower part of the esophagus. The following are additional diseases and conditions that affect the esophagus: Achalasia [1] Acute esophageal necrosis; Barrett's esophagus; Boerhaave syndrome; Caustic injury to the esophagus; Chagas disease
The tumor is solid, hard, irregular ("fir-tree," "moth-eaten", or "sun-burst" appearance on X-ray examination) due to the tumor spicules of calcified bone radiating at right angles. These right angles form what is known as a Codman triangle, which is characteristic but not diagnostic of osteosarcoma. Surrounding tissues are infiltrated.
Because soft tissue is relatively elastic, tumors can grow rather large, pushing aside normal tissue, before they are felt or cause any problems. The first noticeable symptom is usually a painless lump or swelling. As the tumor grows, it may cause other symptoms, such as pain or soreness, as it presses against nearby nerves and muscles.
