invasive vs. non-invasive techniques

Invasive techniques involve entering the body through methods like surgery or inserting instruments, which can provide direct and detailed information but carry risks such as infection or complications. Non-invasive techniques, on the other hand, gather information without breaching the skin, using methods like imaging scans (e.g., X-rays, MRIs) or blood tests from a simple prick. While non-invasive methods are generally safer and more comfortable, they may not always provide as much detail as invasive procedures. Both approaches are valuable in medical diagnosis and treatment, each with its specific applications and benefits.
