When most people think of cancer, they imagine dramatic symptoms sharp pain, a growing lump, or severe weight loss. But here’s the dangerous truth: many cancers start quietly, without causing any noticeable symptoms at all.
Cancer doesn’t always scream. Sometimes, it whispers or says nothing at all.
That’s why awareness and early detection are key to survival.
As Dr. Sudip Shrestha, one of Nepal’s foremost oncologists and Executive Chairman of Nepal Cancer Hospital & Research Center, explains:
“Many cancers are discovered only in the later stages not because they’re fast-growing, but because they stayed hidden. Early screening can catch them when they’re most treatable.”
This blog will walk you through the silent symptoms of cancer, why they matter, and what steps you should take to protect yourself and your loved ones.
The Silent Signs of Cancer You Shouldn’t Ignore
1. Unexplained Fatigue
Feeling tired is normal. But if you’re constantly exhausted without any reason it could be a sign that something is wrong inside your body. Cancer-related fatigue is deeper than everyday tiredness. It doesn’t improve with rest and may worsen over time. Cancers like leukemia, colon, or stomach cancer often cause this type of fatigue due to internal bleeding or immune system disruption.
2. Changes in Bowel or Bladder Habits
Persistent changes in how you go to the toilet like diarrhea, constipation, or difficulty urinating may signal cancer in the colon, rectum, or bladder. You might also notice blood in your stool or urine. These symptoms are easy to dismiss or misattribute to other issues like infections, but if they persist for more than a few days, seek medical evaluation.
3. Persistent Cough or Hoarseness
A cough lasting longer than three weeks, especially if it worsens over time or brings up blood, can be an early warning sign of lung cancer. Similarly, hoarseness that doesn’t go away could indicate laryngeal or thyroid cancer. Don’t ignore your voice or your breath especially if you’re a smoker or have a family history of respiratory diseases.
4. Unusual Bleeding or Discharge
Bleeding between periods, after sex, during menopause, or from the rectum should not be ignored. It could signal cancers of the cervix, uterus, or colon. Likewise, unusual nipple discharge might be an early sign of breast cancer.
5. Slow-Healing Sores or Wounds
A sore that refuses to heal especially in the mouth, on the skin, or on the genitals can be an early indication of skin or oral cancer. These lesions may not cause pain but can quietly grow into serious problems if ignored.
6. Unexplained Weight Loss
Losing weight without dieting or increasing physical activity might seem like a good thing but it can be a warning sign. Unexplained weight loss (more than 5 kilograms) can indicate cancers such as pancreatic, stomach, or esophageal cancer. These types can interfere with your metabolism or appetite.
7. Lumps or Thickening Under the Skin
A painless lump or area of thickening tissue can appear in the breast, testicles, lymph nodes, or soft tissues. While not always cancerous, such growths should be checked immediately, as they could be early indicators of breast, testicular, or lymphatic cancers.
Why Early Detection Saves Lives?
Dr. Sudip Shrestha emphasizes a critical point:
“The earlier we detect cancer, the better the outcome. Many patients survive and thrive simply because they didn’t wait for symptoms to become obvious.”
What Is Cancer Screening?
Cancer screening involves tests and procedures that look for cancer before you have symptoms. This helps detect cancers at an early stage—when treatment is more effective and less aggressive.
Common screenings include:
- Mammograms – for early detection of breast cancer
- Pap smears/VIA tests – for cervical cancer
- PSA blood tests – for prostate cancer
- Fecal occult blood tests or colonoscopy – for colorectal cancer
Who Should Get Screened?
- Women over 40 should get regular mammograms.
- Women aged 21–65 should get cervical cancer screenings.
- Men over 50 should discuss prostate screening with their doctor.
- Everyone over 50 should consider colorectal screening.
- Anyone with a family history of cancer should start screenings earlier.
When to See a Doctor?
If you experience any of the symptoms mentioned above for more than two weeks, consult a doctorespecially if you’re over 40 or have a family history of cancer. You don’t need to feel sick to be sick. Cancer can grow quietly for months or even years.
Dr. Sudip Shrestha and his team at Nepal Cancer Hospital offer comprehensive cancer screenings, early detection programs, and advanced treatments.
