As with most blood tests, false-negatives can happen, meaning results could come back negative when a cancer does exist — although Grail reports that negative cancer test results from Galleri ...
The Papanicolaou test (abbreviated as Pap test, also known as Pap smear (AE), [1] cervical smear (BE), cervical screening (BE), [2] or smear test (BE)) is a method of cervical screening used to detect potentially precancerous and cancerous processes in the cervix (opening of the uterus or womb) or, more rarely, anus (in both men and women).

ectopic pregnancy (2% of cases) normal term pregnancy (20–30% of cases) hyperemesis gravidarum; Rarely, choriocarcinoma occurs in primary locations other than the placenta; very rarely, it occurs in testicles. Although trophoblastic components are common components of mixed germ cell tumors, pure choriocarcinoma of the adult testis is rare.
OGCTs are relatively difficult to detect and diagnose at an early stage because of the nonspecific histological characteristics. [1] Common symptoms of OGCT are bloating, abdominal distention, ascites, and dyspareunia. [1] OGCT is caused mainly due to the formation of malignant cancer cells in the primordial germ cells of the ovary. [1]
The blood test, called Galleri, can detect multiple types of cancer early and targets 80% of cancers currently not screened for that result in cancer deaths, Grail CEO Bob Ragu
The objective of cancer screening is to detect cancer before symptoms appear, involving various methods such as blood tests, urine tests, DNA tests, and medical imaging. [ 1 ] [ 2 ] The purpose of screening is early cancer detection, to make the cancer easier to treat and extending life expectancy. [ 3 ]
Cancers are usually named using -carcinoma, -sarcoma or -blastoma as a suffix, with the Latin or Greek word for the organ or tissue of origin as the root. For example, the most common cancer of the liver parenchyma ("hepato-" = liver), arising from malignant epithelial cells ("carcinoma"), would be called a hepatocarcinoma , while a malignancy ...

[1] About 90% of these new cases and deaths of cervical cancer occurred in low- and middle-income countries. [1] Roughly 1% of sexually active adults have genital warts. [11]
