Kim and Khloe Kardashian, along with mama Kris Jenner, took a trip to San Diego Tuesday to get tested to see if they carried a genetic cancerous gene.
The women, accompanied by Dr. Paul Nassif from "Botched," went to Pathway Genomics, a company that tests for BRCA1 ... a gene mutation that causes a high likelihood of breast and ovarian cancer.
Angelina Jolie famously had preventive surgery after she tested positive. They were also tested for heart disease and diabetes.
The patriarch of Kim's family -- Robert Kardashian -- died of cancer at 59.
No one revealed the results.
