High Risk, Big Decisions: What Every Previvor Should Know
What It Means to Be High Risk: The Previvor Journey Is Real, Too
Being high risk is not the same as having cancer — but it is still a real and deeply emotional journey. For many women, it means living with uncertainty, making preventative decisions, and carrying the weight of “what if” long before a diagnosis ever happens.
Important: I’m not a doctor. This is educational information, not medical advice. Genetic results, family history, age, fertility goals, and personal values all matter when making decisions. If you have tested positive for a cancer-related gene mutation, a genetic counselor and your care team should help guide next steps.
High risk is a different journey — but it is still a real one
When a woman is diagnosed with cancer, the path ahead often becomes immediate: scans, specialists, treatment plans, surgery, chemotherapy. When a woman is told she is high risk, the journey looks different — but it can be just as heavy in its own way.
High-risk women are often asked to make decisions about increased screening, preventative surgery, fertility, family planning, menopause, and body image before cancer is ever part of their story. That experience is often called previvorship — living with the emotional, physical, and practical impact of elevated cancer risk.
You may not have cancer, but you may still be grieving. You may still feel afraid. You may still be trying to understand what your future looks like. That deserves support too.
What genes are women commonly tested for?
If your doctor or family history suggests hereditary cancer risk, you may be offered genetic testing. Some of the most common genes on hereditary breast and gynecologic cancer panels include:
- BRCA1 and BRCA2
- PALB2
- CHEK2
- ATM
- TP53
- PTEN
- CDH1
- Lynch syndrome genes such as MLH1, MSH2, MSH6, PMS2, and EPCAM
Not every gene carries the same risk, and not every positive result leads to the same recommendation. Some mutations are associated more strongly with breast cancer, some with ovarian or uterine cancer, and some with colorectal cancer as well.
Quick reference: what some of these genes can mean
| Gene | What it may increase risk for | What doctors may discuss | Why it feels so big emotionally |
|---|---|---|---|
| BRCA1 | Markedly higher lifetime risk of breast cancer and ovarian cancer | Earlier MRI/mammogram screening, risk-reducing mastectomy, and later removal of fallopian tubes/ovaries after childbearing | You may be asked to consider major surgery to prevent a cancer you do not currently have. |
| BRCA2 | Markedly higher lifetime risk of breast cancer and elevated ovarian cancer risk | Enhanced screening, possible mastectomy discussion, and possible salpingo-oophorectomy depending on age and family history | The future can suddenly feel more medical, more urgent, and less certain. |
| PALB2 | Elevated breast cancer risk | More aggressive screening and sometimes surgery conversations depending on family history | You may not know this gene as well as BRCA, but the decisions can still feel enormous. |
| CHEK2 / ATM | Moderate increased breast cancer risk in many carriers | Enhanced surveillance and individualized prevention planning | The uncertainty can be difficult because the answer is not always “do surgery” or “don’t do surgery.” |
| TP53 / PTEN / CDH1 | Can be associated with higher and broader hereditary cancer risk syndromes | Intensive screening and specialty discussions depending on syndrome and family history | The rarity of these syndromes can make women feel especially isolated and frightened. |
| Lynch syndrome genes | Elevated risk of endometrial, ovarian, and colorectal cancer | Colonoscopies, gynecologic surveillance, and sometimes hysterectomy with removal of tubes/ovaries after childbearing | It can shift the conversation from breast screening alone to multiple organs and life-stage decisions. |
What do BRCA1 and BRCA2 actually mean?
BRCA1 and BRCA2 are the most widely known hereditary breast and ovarian cancer genes. Women who inherit a harmful variant in either gene face a much higher lifetime risk of breast cancer than the general population.
In plain language:
- Women with a harmful BRCA1 or BRCA2 variant have a lifetime breast cancer risk of more than 60%.
- Lifetime ovarian cancer risk is estimated at roughly 39%–58% for BRCA1 carriers.
- Lifetime ovarian cancer risk is estimated at roughly 13%–29% for BRCA2 carriers.
That is why some women are offered very different prevention plans than average-risk patients.
These results do not tell you if or when cancer will happen. But they do shift the conversation from routine screening to proactive risk management.
What surgeries might women hear about?
This is often the hardest part of the high-risk journey: being asked to consider life-changing surgery for a cancer that has not happened.
Common conversations may include:
- Risk-reducing bilateral mastectomy to significantly lower future breast cancer risk
- Risk-reducing salpingo-oophorectomy to lower ovarian cancer risk by removing the fallopian tubes and ovaries
- Hysterectomy in some women with Lynch syndrome because of elevated endometrial cancer risk
For BRCA carriers, risk-reducing mastectomy can lower breast cancer risk by at least 90%. Removal of the tubes and ovaries can also greatly reduce ovarian cancer risk in appropriate patients.
But statistics do not make these decisions easy. These choices affect fertility, hormones, sexual health, body image, recovery, and identity. For many women, the grief is real even when the decision is clearly preventive.
How is the previvor journey different from a diagnosed journey?
A diagnosed woman is often thrown into treatment. A high-risk woman is thrown into uncertainty.
She may look “fine” to everyone else, while internally carrying fear every day. She may be deciding whether to remove healthy breasts, ovaries, or her uterus in order to reduce the risk of something that has not happened. She may be planning surgeries while still trying to explain to others why she needs support at all.
That is why previvorship can feel so isolating. The emotional burden is real, even if the diagnosis is not.
If you test positive, what happens next?
A positive genetic result should not send you into panic. It should connect you to the right team.
- A genetic counselor to help explain your result clearly
- A breast specialist to discuss imaging and prevention options
- A gynecologic specialist if ovarian, uterine, or fallopian tube risk is elevated
- Additional specialists depending on the syndrome and family history
Your next steps may include earlier screening, more frequent imaging, fertility planning, surgery conversations, family testing, or simply time to process before making decisions.
A positive result does not automatically mean one path. It means you deserve a thoughtful one.
The emotional truth of being high risk
Being high risk can mean carrying the emotional weight of cancer before cancer ever happens.
It can mean fear before a scan, guilt around family genetics, pressure around surgery, and grief over the idea of losing parts of your body in the name of prevention.
If that is where you are, you are not overreacting and you are not “too early” to need support. This is a real chapter of the journey.
