Weeks 1 & 2. During the first few weeks of pregnancy, your progesterone levels will be roughly 1-1.5ng/ml. Keep in mind that the gestational age of your baby is calculated from the start of your last menstrual period â even though you werenât pregnant at this time.
No. Cancer is not really hereditary in the true sense of the word. Hereditary means that you definitely get a trait such as eye colour or an illness from the genes you inherit from your parents. The cause of cancer is not as simple as that. Cancers are not caused by just one gene. Cancer is usually an illness of older people and most cancers occur when several genetic changes occur in a cell. This is called sporadic cancer. But some people inherit faulty (mutated) genes which make their chance of developing a particular cancer higher than normal.
Genetic risk factors. About 5% to 10% of breast cancer cases are thought to be hereditary, meaning that they result directly from gene defects (called mutations) inherited from a parent. BRCA1 and BRCA2: The most common cause of hereditary breast cancer is an inherited mutation in the BRCA1 and BRCA2 genes. People with this syndrome have an increased risk of breast cancer, as well as several other cancers such as leukemia, brain tumors, and sarcomas (cancers of bones or connective tissue). 2  This is a rare cause of breast cancer. 3  CHEK2: The Li-Fraumeni syndrome can also be caused by inherited mutations in the CHEK2 gene.
