Inherited Cancer Risk Review
Adults 18 and older can review a personal or family pattern that raises an inherited-cancer question. The National Cancer Institute says about 5-10% of cancers are thought to come from an inherited harmful change. Shared tobacco can cluster cancers without a syndrome. Counseling and hereditary testing are not done here. Nutrition, methylation, and celiac panels do not test cancer-risk genes. A referral is not acceptance.
Symptoms and questions to discuss
- Cancer at a young age, or several close relatives with the same cancer
- Several cancers in one person, or both organs of a pair
- A known cancer-gene change in the family
- Colorectal cancer before 50, ovarian, pancreatic, or male breast cancer, or metastatic prostate cancer
- A mail-in BRCA report that is hard to interpret
What we check
- Cancer type and age for close relatives on both sides
- Any known family variant, prior test, or mail-in report
- Personal cancers that guidelines flag for a genetics consultation
- Whether the pattern is BRCA-related, another syndrome, or neither
- Symptoms that need diagnosis now rather than a counseling date
Treatment options by class
Your provider reviews appropriate options and follow-up based on your assessment.
- A both-sides family history with cancer type and age
- A brief familial risk tool only when the pattern is BRCA-related
- A request for outside genetic counseling before any hereditary test
- A separation of nutrition, methylation, and celiac panels from cancer-risk testing
When we refer
Outside genetics professionals choose and interpret hereditary tests. Results are not a treatment plan here. People in cancer treatment keep oncology. A high-risk syndrome requires a specialist screening plan instead of the average-risk schedule. No counselor, laboratory, or appointment is confirmed.
Patterns that change the plan
Record cancer type and age on both sides. The plan can change for a known family gene change, young cancer such as colon before 50, several cancers in one person or in close relatives, breast with ovarian cancer, colon with endometrial cancer, both of a paired organ, or male breast cancer. Triple-negative breast, ovarian, pancreatic, colorectal before 50, metastatic prostate, and male breast cancer go to outside genetics. This clinic does not order that test. A BRCA-related pattern uses a brief primary-care tool for women with personal or family breast, ovarian, tubal, or peritoneal cancer, or ancestry linked to BRCA1 or BRCA2. A positive tool means counseling, then testing only if indicated. Routine testing is not recommended without that history. The tool is not every syndrome. Lynch syndrome and familial adenomatous polyposis leave average-risk colon screening.
Counseling and testing stay outside
Counseling comes before testing and again after a positive result. A genetics professional does it, not this clinic. There is no hereditary laboratory here. Start with a relative who had cancer when possible. Nutrition, methylation, and celiac panels are not BRCA tests. A tumor test is not a hereditary test. A referral is not an appointment.
What a gene result means
A positive test means higher risk, not cancer now. A true negative for a known family variant generally approaches population risk; other history still matters. An uninformative negative can leave extra risk. An uncertain variant should not set treatment or screening by itself. Mail-in tests examine selected variants, not all harmful cancer-risk changes. A negative result does not exclude inherited risk; a positive result needs clinical confirmation before decisions. An outside genetics professional chooses and interprets testing, explains family implications, and sets any reclassification follow-up. Confirm report receipt, acceptance, availability and cost.
Danger signs do not wait
Call 911 for heavy bleeding, vomiting blood, sudden breathlessness, chest pain, severe pain, sudden weakness, confusion, or trouble speaking. Do not wait for counseling. A new lump, bleeding after menopause, stool blood, or a lasting cough needs prompt diagnosis. During cancer treatment, or with low immunity, fever of 100.4°F (38°C) or higher is emergency care.
Frequently asked questions
Does family cancer mean I inherited it?
Usually no. About 5-10% are thought to come from an inherited harmful change. Some patterns still change screening.
Will this visit include a BRCA blood test?
No. Testing is outside, after counseling, and only if the history fits.
Do nutrition or celiac panels measure cancer risk?
No. They are not cancer-risk tests. A normal panel does not replace screening.
My mail-in BRCA test was negative. Am I done?
No. Selected-variant consumer tests can miss inherited risk. Bring the actual report and family history to an outside genetics professional; do not change screening or treatment from that result alone.
Who explains an uncertain variant?
A genetics professional. This clinic does not interpret hereditary results.
