Cancer is one of the leading causes of death worldwide, but early detection can significantly improve survival rates. While the word “cancer” can evoke fear, knowledge is a powerful tool in combating this disease. By understanding the most common types of cancer and their symptoms, you can be more vigilant about your health and recognize potential warning signs early on. In this article, we’ll explore the five most prevalent types of cancer, highlight their symptoms, and provide insight into what you should look out for to protect your health.
1. Breast Cancer
Breast cancer is the most commonly diagnosed cancer in women, but it can also affect men. Early detection plays a crucial role in successful treatment, making it vital to be aware of the symptoms. The most common symptom of breast cancer is a lump or mass in the breast tissue.1
Not all lumps are cancerous, but any new or unusual growth should be checked by a healthcare professional. Other symptoms include changes in the size or shape of the breast, dimpling or puckering of the skin, and nipple discharge that isn’t breast milk. Some people may also experience redness or flaky skin around the nipple area. Regular self-examinations and mammograms are key to catching breast cancer early, especially for those with a family history of the disease.
2. Lung Cancer
Lung cancer is the leading cause of cancer death worldwide, affecting both smokers and non-smokers. Despite its high mortality rate, lung cancer often goes undetected in its early stages because symptoms can be mistaken for other respiratory conditions. The most common symptoms of lung cancer include a persistent cough that doesn’t go away, coughing up blood, shortness of breath, and chest pain.
These symptoms can be subtle at first, which is why many people may dismiss them as a result of a cold, allergies, or a lingering infection. Fatigue and unexplained weight loss are also signs to watch for. If you’re a smoker or have been exposed to secondhand smoke, it’s especially important to be mindful of these symptoms and seek medical attention if they persist.
3. Colorectal Cancer
Colorectal cancer, which includes cancers of the colon and rectum, is another common type that affects both men and women. It often begins as noncancerous polyps in the colon or rectum, which can develop into cancer over time. Screening through colonoscopies can help detect and remove these polyps before they become problematic.
Symptoms of colorectal cancer can vary, but some of the most common include changes in bowel habits, such as diarrhea, constipation, or a change in stool consistency. Blood in the stool, abdominal pain or cramping, and a feeling of incomplete bowel evacuation are also common warning signs. Additionally, unexplained weight loss and fatigue may indicate the presence of colorectal cancer. Since symptoms can be subtle and easily attributed to other digestive issues, regular screenings are important, especially for those over the age of 50 or with a family history of the disease.
4. Prostate Cancer
Prostate cancer is one of the most common cancers among men, particularly those over the age of 50. It typically grows slowly and may not show symptoms in its early stages, which is why routine screenings like prostate-specific antigen (PSA) tests are vital for early detection.
When symptoms do appear, they often involve urinary issues. Men may experience difficulty starting or stopping urination, a weak or interrupted urine flow, and a frequent need to urinate, especially at night. Some men may also notice blood in their urine or semen, and experience discomfort or pain in the pelvic area. Erectile dysfunction can also be a symptom of prostate cancer. While these symptoms may be caused by other conditions, such as benign prostatic hyperplasia (BPH), it’s important to consult a healthcare provider for further evaluation.
5. Skin Cancer
Skin cancer is the most common cancer worldwide, and it comes in several forms, including melanoma, basal cell carcinoma, and squamous cell carcinoma. The most serious type, melanoma, can be life-threatening if not detected early, but all types of skin cancer can cause significant damage if left untreated. Skin cancer symptoms typically manifest as changes in the skin.2
This can include new growths, sores that don’t heal, or changes in existing moles. The ABCDE rule is a helpful guide to identifying potential melanomas: Asymmetry, Border irregularity, Color variation, Diameter larger than 6mm, and Evolving in size, shape, or color. People with fair skin, a history of sunburns, or excessive exposure to UV radiation are at higher risk for skin cancer. Regular self-examinations and dermatologist check-ups are crucial for catching skin cancer early.
