Relying solely on routine tests is not enough to safeguard against cancer. It is equally crucial to pay attention to your body and recognize any unusual, peculiar, or inexplicable changes. Here are indications that are frequently disregarded:

1. Wheezing or Shortness of Breath:
   Lung cancer patients often recall their initial symptom as difficulty catching their breath.
2. Chronic Cough or Chest Pain:
   Various cancers, such as leukemia and lung tumors, can exhibit symptoms resembling a persistent cough or bronchitis. Some individuals with lung cancer experience chest pain extending to the shoulder or down the arm.
3. Frequent Fevers or Infections:
   These may signal leukemia, a blood cell cancer affecting the bone marrow, compromising the body’s ability to fight infections.
4. Difficulty Swallowing:
   Primarily associated with esophageal or throat cancer, trouble swallowing can also be an early sign of lung cancer.
5. Swollen Lymph Nodes or Lumps:
   Enlarged lymph nodes indicate changes in the lymphatic system, potentially signifying cancer.
6. Excessive Bruising or Bleeding:
   Abnormal platelet and red blood cell activity, often indicative of leukemia, can lead to unexplained bruising and bleeding.
7. Weakness and Fatigue:
   Generalized fatigue is a common symptom across various cancers and should be considered in conjunction with other signs.
8. Bloating or Abdominal Weight Gain:
   Ovarian cancer is frequently associated with unexplained abdominal bloating that persists intermittently.
9. Feeling Full and Unable to Eat:
   Another indicator of ovarian cancer is a lack of appetite and the inability to eat, even after a prolonged period without food.
10. Pelvic or Abdominal Pain:
    Pain and cramping in the pelvis and abdomen may accompany bloating, often a signal of ovarian cancer.
11. Rectal Bleeding or Blood in Stool:
    A common indicator of colorectal cancer, blood in the stool necessitates a doctor’s attention and a colonoscopy.
12. Unexplained Weight Loss:
    Early weight loss can point to digestive cancers like colon cancer or metastasized cancer affecting the liver.
13. Upset Stomach or Stomachache:
    Colorectal cancer may manifest with stomach cramps or frequent upset stomachs.
14. Red, Sore, or Swollen Breast:
    Inflammatory breast cancer can present with redness, soreness, or swelling. Any breast changes should prompt a doctor’s consultation.
15. Nipple Changes:
    A flattened, inverted, or sideways-turned nipple can be a common early sign of breast cancer.
16. Unusually Heavy or Painful Periods:
    Endometrial or uterine cancer may be indicated by significant menstrual changes. Transvaginal ultrasound is recommended for suspected issues beyond routine heavy periods.
17. Swelling of Facial Features:
    Some lung cancer patients observe puffiness, swelling, or redness in the face due to blocked blood vessels.
18. Sore or Skin Lump:
    Different types of skin cancer, including melanoma, basal cell carcinoma, and squamous cell carcinoma, should be monitored for changes or abnormalities.
19. Changes in Nails:
    Fingernail alterations can signal various cancers, such as a streak or dot under the nail indicating skin cancer and “clubbing” possibly pointing to lung cancer.
20. Pain in the Back or Lower Right Side:
    Liver cancer may manifest as back pain, and breast cancer is sometimes diagnosed through back pain when a tumor affects the spine or ribs.
