Internal surgeries are medical procedures performed inside the body to treat various conditions. These surgeries can involve organs such as the heart, lungs, or stomach. They are often necessary to remove tumors, repair damaged tissues, or address issues like appendicitis. Surgeons use specialized tools and techniques, often employing minimally invasive methods like laparoscopy, which involves small incisions and the use of a camera. Recovery times can vary depending on the type of surgery and the patient's overall health, but many people can return to normal activities within weeks.
