Thank you for the query.
Lower left abdominal pain can be caused by diverticulitis
, urinary tract infection
, ovarian cyst. Ovarian cancer can also give such symptom as well as ovarian cyst. Stomach pain seems to be caused by stomach disease
like peptic ulcers or acid reflux disease. Sharp pain in the chest can appear due to rib nerves irritation. But most likely your stomach pain and sharp chest pain is caused by stress (as you have admitted to be scared about cancer, this can trigger such symptoms).
If an ovarian cancer runs in your family (and maybe breast cancer?) you should consult oncologist
as some of such hereditary cancers are caused by genes mutations. You should have checked BRCA1/BRCA2 mutations. Ca-125 level and transvaginal ultrasound
should be also performed.
Lower abdominal pain should be consulted with gastroenterologist and some blood tests and urine tests should be performed.
Hope this will help.
