Luminous refers to something that gives off light, typically in the form of glow or radiance. It can also describe something that is shinning brightly, radiant, and full of light.
A luminometer is a device used to measure the intensity of light emitted by a sample, typically in bioluminescence assays. It is often used in scientific research and quality control to determine the amount of light produced by a biological or chemical reaction. The luminometer is usually based on a photomultiplier tube (PMT) or a light sensor that converts the light into an electrical signal, which is then measured and displayed as a unified index of light emission.
A lumpectomy is a surgical procedure in which a tumor or abnormal tissue is removed from the breast. It is also known as breast-conserving surgery or wide-local excision. The goal of a lumpectomy is to remove as much of the tumor as possible while preserving as much of the surrounding breast tissue as possible. This type of surgery is often used to treat early-stage breast cancer or ductal carcinoma in situ (DCIS).
