Do I Have Cancer? Understand Symptoms and Screening Tests

Could My Symptoms Mean Cancer? Understanding Your Risk

Feeling under the weather? Have some strange symptoms you can't explain? It's normal to worry "do I have cancer?" when new symptoms arise. While it's best not to panic or diagnose yourself via an online cancer quiz, understanding key risk factors, changes to watch for, screening tools and testing options can help assess if cancer may be a possible cause of your symptoms.

Most Common Cancer Types

Cancers can develop anywhere in the body when cells grow out of control. The most prevalent cancer types include:

• Breast cancer
• Lung cancer
• Prostate cancer
• Colon and rectal cancer
• Skin cancer
• Bladder cancer
• Uterine cancer
• Thyroid cancer
• Kidney cancer
• Leukemia (blood cancer)

Understanding Cancer Risk Factors

While cancer can happen to anyone, certain risk factors are linked to higher odds of developing the disease. Risks include:

• Increasing age
• Tobacco use including smoking
• Sun exposure and tanning bed use
• Radon gas exposure
• Asbestos exposure
• Chemicals exposure
• Drinking excess alcohol
• Poor diet and inactivity
• Obesity
• Chronic inflammation or infections
• Family history and inherited gene mutations

Spotting Possible Cancer Signs and Symptoms

In many cases early cancer symptoms seem vague or mimic other common conditions, making the disease hard to recognize. Thats why cancer screening tests and awareness of key changes are so important.

Tell your doctor about any unusual symptoms or health changes that:

• Persist beyond two weeks
• Worsen over time
• Disrupt sleep
• Don't respond to over-the-counter medications

Possible cancer symptoms can include:

• Unexplained weight loss
• Fever and chills
• Fatigue or weakness
• Skin changes like yellowing, darkening mole, a sore or lump
• Changes in bowel or bladder function
• Nagging cough or trouble breathing
• Indigestion or difficulty swallowing
• Unusual bleeding or discharge
• Headaches and pain that won't go away

Available Cancer Screening and Diagnostic Tests

If you have any worrisome symptoms or are at higher risk for cancer, your doctor can recommend appropriate screening tests even before a diagnosis. Screenings aim to detect cancer early when it may respond best to treatment. If screens are abnormal, doctors then order diagnostic tests to confirm if cancer is present and identify details to guide treatment.

Screening Tools by Cancer Type

Recommended regular screening tests based on a person's age, gender, health history and risk factors may include:

• Breast exam - Clinical breast exam by doctor to feel for lumps starting at age 20.
• Mammograms - Annual breast X-rays, starting ages 40-45.
• Skin exam - Full body skin check for moles and lesions, starting age 18.
• Colonoscopy - Exam of full colon with a camera scope, starting age 45.
• Pap and HPV tests - Sample of cervical cells to screen for cervical cancer risk, starting age 21.
• PSA blood test - Screens for prostate cancer risk in men, starting age 55.
• Low-dose CT scan - Imaging test to detect lung cancer, ages 55-80 with long smoking history.

Screening tests are also available for other cancer types like oral, liver, pancreatic, ovarian and more for those meeting guidelines.

Diagnostic Tests to Confirm Cancer

If screening results are abnormal or concerning symptoms arise, doctors order diagnostic tests. These aim to analyze suspicious cells or areas and confirm whether cancer is present. Diagnostic tools include:

• Imaging tests - CT scan, PET scan, ultrasound, MRI and X-ray views.
• Biopsy - Removing a small tissue sample to examine cells under a microscope.
• Blood tests - Complete blood count, tumor marker and genetic tests check for cancer markers.
• Endoscopy - Snaking a lighted camera tube into the throat, bowel or body cavity to view internal tissues.
• Bone marrow aspiration - Drawing bone marrow fluid to analyze blood cell disorders like leukemia.

These specialized tests help definitively diagnose cancer type and stage to guide appropriate treatment.

Making Sense of Cancer Screening Results

Waiting and wondering "do I have cancer?" after getting screened can induce lots of anxiety. But most screening tests yield normal, negative results. Here's an overview of common outcomes:

Normal Result

A normal, negative screen suggests tissues appear healthy with no clear evidence of cancer. Normal findings provide peace of mind and indicate safe waiting times until the next recommended screening based on personal risk factors.

Inconclusive Finding

Sometimes screens can be difficult to interpret due to image quality, sample size or other technical factors. An inconclusive result means another similar screen will usually need repeating in the near future to reassess.

Abnormal Finding

An abnormal screening result indicates potential unhealthy cell changes requiring further testing. It does not mean you definitely have cancer. But more sensitive diagnostic testing is warranted to investigate further.

Positive Cancer Diagnosis

If you undergo diagnostic testing after an abnormal screen and tests confirm a cancer is present, next steps are to identify details like: type of cancer, location, size, stages and biomarkers. This data will inform discussions of treatment options with your oncology team.

Available Treatment Options by Cancer Type and Stage

If diagnosed with cancer, key factors determining your prognosis and treatment options include: cancer type, location, size, stages and biomarkers.

Common Treatment Types

Today more people are living longer and better after a cancer diagnosis thanks to advanced treatment options. Your doctor may recommend combining several tactics such as:

• Surgery - To remove tumors and affected tissue.
• Chemotherapy - Using anti-cancer drugs to kill harmful cells.
• Radiation - High energy beams to destroy and shrink tumors.
• Targeted therapy - Drugs focused on specific genes and proteins that enable cancer growth.
• Immunotherapy - Harnessing your immune system to attack cancer cells.
• Hormone therapy - Blocking or reducing hormones linked to some cancers.

You'll work closely with your care team to develop a customized treatment plan aiming to cure the cancer, control growth, help you feel better by easing symptoms, or some combination thereof based on the scenario.

Importance of Early Detection

When detected at an early stage before spreading throughout the body, many cancer types have very high cure rates with treatment. Unfortunately, later stage cancers that have advanced locally or metastasized (spread) to other areas of the body can be harder
