Cancer In Adolescents And Young Adults
Cancer in adolescents and young adults is cancer which occurs in those between the ages of 15 and 39. This occurs in about 70,000 people a year in the United States—accounting for about 5 percent of cancers. This is about six times the number of cancers diagnosed in children ages 0–14. Globally, nearly 1 million young adults between the ages of 20 and 39 were diagnosed with cancer in 2012, and more than 350,000 people in this age range died from cancer. Young adults are more likely than either younger children or older adults to be diagnosed with certain cancers, such as Hodgkin lymphoma, testicular cancer, and some types of sarcomas. In adolescents and young adults 15 to 24 years old, lymphoma, testicular cancer, and thyroid cancer are the most common types, while among 25- to 39-year-olds, breast cancer and melanoma are more common. Definition People who are diagnosed with cancer between the ages of 15 and 39 fit the definition of "adolescent and young adults" according to ...

Oncology
Oncology is a branch of medicine that deals with the study, treatment, diagnosis and prevention of cancer. A medical professional who practices oncology is an ''oncologist''. The name's etymological origin is the Greek word ὄγκος (''ónkos''), meaning "tumor", "volume" or "mass". Oncology is concerned with: * The diagnosis of any cancer in a person (pathology) * Therapy (e.g. surgery, chemotherapy, radiotherapy and other modalities) * Follow-up of cancer patients after successful treatment * Palliative care of patients with terminal malignancies * Ethical questions surrounding cancer care * Screening efforts: ** of populations, or ** of the relatives of patients (in types of cancer that are thought to have a hereditary basis, such as breast cancer) Diagnosis Medical histories remain an important screening tool: the character of the complaints and nonspecific symptoms (such as fatigue, weight loss, unexplained anemia, fever of unknown origin, paraneoplastic phenome ...

Oral Cancer
Oral cancer, also known as mouth cancer, is cancer of the lining of the lips, mouth, or upper throat. In the mouth, it most commonly starts as a painless white patch, that thickens, develops red patches, an ulcer, and continues to grow. When on the lips, it commonly looks like a persistent crusting ulcer that does not heal, and slowly grows. Other symptoms may include difficult or painful swallowing, new lumps or bumps in the neck, a swelling in the mouth, or a feeling of numbness in the mouth or lips. Risk factors include tobacco and alcohol use. Those who use both alcohol and tobacco have a 15 times greater risk of oral cancer than those who use neither. Other risk factors include HPV infection, chewing paan, and sun exposure on the lower lip. Oral cancer is a subgroup of head and neck cancers. Diagnosis is made by biopsy of the concerning area, followed by investigation with CT scan, MRI, PET scan, and examination to determine if it has spread to distant parts of the body. ...

Embryo Cryopreservation
Cryopreservation of embryos is the process of Cryopreservation, preserving an embryo at sub-zero temperatures, generally at an embryogenesis stage corresponding to pre-implantation, that is, from fertilisation to the blastocyst stage. Indications Embryo cryopreservation is useful for leftover embryos after a cycle of in vitro fertilisation, as patients who fail to conceive may become pregnant using such embryos without having to go through a full IVF cycle. Or, if pregnancy occurred, they could return later for another pregnancy. Spare oocytes or embryos resulting from fertility treatments may be used for oocyte donation or embryo donation to another woman or couple, and embryos may be created, frozen and stored specifically for transfer and donation by using donor eggs and sperm. Method Embryo cryopreservation is generally performed as a component of in vitro fertilization (which generally also includes Controlled ovarian hyperstimulation, ovarian hyperstimulation, egg retrieval a ...

Oocyte Cryopreservation
Human oocyte cryopreservation (egg freezing) is a procedure to preserve a woman's eggs ( oocytes). This technique has been used to enable women to postpone pregnancy to a later date – whether for medical reasons (such as cancer treatment), or for social reasons (such as employment or studying). Several studies have shown that most infertility problems are due to germ cell deterioration related to aging. The intention of the procedure is that the woman may choose to have the eggs thawed, fertilized, and transferred to the uterus as embryos to facilitate a pregnancy in the future. The procedure's success rate (the chances of a live birth using frozen eggs) varies depending on the age of the woman, with odds being higher in younger, adult women. Indications Oocyte cryopreservation can increase the chance of a future pregnancy for three key groups of women: # those diagnosed with cancer who have not yet begun chemotherapy or radiotherapy; # those undergoing treatment with assis ...
