Cancer Questions

Q: Is it a fact that cancer is also genetically inherited? If so, how much percentage of cancer affected patients have genetically inherited cancer? 

K: While most cancers are not directly inherited, some cancers are linked to inherited genetic mutations that increase a person's risk of developing the disease. These inherited mutations, present in the egg or sperm cells, can be passed down from parent to child, potentially leading to a higher risk of certain cancers. However, inheriting a cancer-related gene doesn't guarantee the development of cancer, and many cancers arise from genetic changes that occur during a person's lifetime.

While a family history of cancer can indicate an increased risk, it doesn't always mean there's an inherited genetic mutation. Other factors like shared environments, lifestyle, or genetic markers can also contribute.

Approximately 5-10% of all cancers are thought to be linked to inherited genetic mutations.

Inherited gene mutations can increase the risk of cancers like breast, ovarian, colon, and prostate cancer.

Q: What are the early detections of cancer?

K: Early cancer detection involves a combination of regular screenings, awareness of potential symptoms, and proactive health practices. Screening tests like mammograms for breast cancer and colonoscopies for colorectal cancer can detect issues before symptoms appear. Additionally, being aware of potential symptoms such as unexplained weight loss, persistent cough, or changes in bowel habits can prompt earlier consultation with a healthcare provider.

Screening Tests:

Mammograms: For breast cancer, these can detect tumors before they are palpable.

Pap smears and HPV tests: For cervical cancer, these can identify precancerous changes.

Colonoscopies: For colorectal cancer, these can find and remove precancerous polyps and early-stage cancers.

Low-dose CT scans: For lung cancer, these can detect tumors in high-risk individuals.

Self-Exams: Regularly checking for unusual lumps or skin changes can help detect potential issues early.

Symptoms to be Aware Of:

Unexplained weight loss.

Persistent cough or hoarseness.

Changes in bowel or bladder habits.

Unusual bleeding or discharge.

Lumps or thickening in the breast or elsewhere.

Indigestion or difficulty swallowing.

Skin changes, including new moles or changes in existing ones.

Nagging cough or hoarseness.

Q: Because my closest relative showed no symptoms till 3rd stage of ovarian cancer.

K: Sorry to hear that and I know you are very concerned about her condition.

Yes, most people cannot find out about their cancer until it is too late. Even if there are a few subtle ones, it is difficult to tie them to cancer.

But it is the way cancer works.
