Pancreatic Cancer

#pancreatic cancer, #chemotherapy, #abdominal CT, #jaundice, #chronic pancreatitis

Pancreatic cancer is cancer that develops in the pancreas, an organ located deep within the body. Because it produces few early symptoms, it is often found at a later stage. Please do not attempt to self-diagnose using an online encyclopedia; if you notice any concerning symptoms, be sure to see a gastroenterology or hepatobiliary-pancreatic surgery specialist.

A pituitary tumor is a tumor that develops in the pituitary gland, a small organ in the middle of the brain. Most are benign tumors and are not cancer. As the tumor grows or hormone secretion is disrupted, various symptoms can appear, so if you have suspected symptoms, please consult a medical specialist.

Postoperative Precautions for Patients With Solid Tumors

#solid tumor, #body swelling, #facial swelling, #leg swelling, #swelling of hands and feet

A solid tumor is a cancer that forms a mass, as opposed to 'liquid' cancers such as blood cancers (hematologic malignancies). Most cancers are solid tumors. Postoperative precautions are as follows.

Prostate Cancer

#prostate cancer, #PSA, #prostate-specific antigen, #robotic surgery, #radiation therapy, #prostate biopsy, #family history, #androgen deprivation therapy, #early screening

Prostate cancer often has no symptoms in its early stages, so it is frequently discovered only after it has progressed significantly. Early detection is possible through the PSA (prostate-specific antigen) blood test, and when found early, surgery or radiation therapy can offer a favorable outlook. Regular screening is important for men age 45 and older, especially those with a family history.

Rectal Cancer

Rectal cancer is a malignant tumor that develops in the rectum, the final section of the large intestine. It often causes almost no symptoms in its early stages and is frequently found incidentally, which makes regular screening very important. If you suspect this condition, please do not try to judge it yourself — be sure to see a medical specialist for a proper evaluation and testing.

Robotic Hepatobiliary and Pancreatic Surgery

#robotic surgery, #laparoscopic surgery, #hepatobiliary and pancreatic surgery, #liver donation, #minimally invasive surgery, #living donor liver transplantation, #surgical scar, #open surgery, #lack of energy, #lethargy, #persistent fatigue

Robotic surgery is a method in which the surgeon sits at a console (control device) and operates by controlling robotic arms. Using 10x magnified three-dimensional (3D) images and freely moving robotic arms, it can allow more precise manipulation than laparoscopic surgery. It is also used for liver, bile duct, and pancreatic surgery, and for liver donation surgery. Whether robotic surgery is suitable, and which method is used, depends on each patient's condition, so please consult a medical specialist.

Robotic Surgery for Gastric Cancer

#gastric cancer, #robotic surgery, #gastrectomy, #laparoscopy, #minimally invasive surgery, #gastric cancer surgery, #chemotherapy, #gastric cancer stage, #hand tremor, #body tremor

Robotic surgery for gastric cancer is a minimally invasive operation in which a surgeon controls a robot to treat gastric cancer. 'Minimally invasive' refers to a method of operating through only small openings in the body. The surgical method (open, laparoscopic, or robotic) is decided by your treating specialist after considering society guidelines, the latest research findings, and the patient's condition together. Please discuss the most suitable surgical method thoroughly with your treating specialist.

Schizophrenia

Schizophrenia is a major mental illness in which the ability to distinguish reality from one's own thoughts and perceptions is impaired. In Korean, the disorder was previously called jeongsinbunyeolbyeong (literally, "split-mind disease") but was renamed johyeonbyeong in 2011; the new term means "tuning the strings," reflecting the idea that mental confusion arises when the brain's neural signaling is not properly tuned. With appropriate treatment and management, people with schizophrenia can maintain daily functioning.

Soft tissue sarcoma is a malignant tumor (cancer) that arises in the soft tissues of the body, such as muscle, fat, blood vessels, nerves, and connective tissue. It is a very rare cancer, and early detection and treatment are important. If you have a lump on your body that keeps growing over several months, please consult a medical specialist.

Sphincter-Preserving Surgery for Rectal Cancer

#rectal cancer, #sphincter preservation, #ostomy, #low anterior resection, #Kegel exercises

Whether the anus can be preserved during rectal cancer surgery depends on the location of the tumor and whether it has invaded the anal sphincter. Because this directly affects quality of life, please consult an experienced colorectal surgeon for an accurate diagnosis and treatment.
