How long can you have cancer and not know it? Early detection? ›

If you're wondering how long you can have cancer without knowing it, there's no straight answer. Some cancers can be present for months or years before they're detected. Some commonly undetected cancers are slow-growing conditions, which gives doctors a better chance at successful treatment.

Several types of cancer do not show symptoms until they progress into advanced stages. Therefore, it is necessary for individuals, especially those with higher risk, to monitor their symptoms. They must consult their doctor if there is any concern about the signs.

Sometimes, a cancer diagnosis comes out of the blue, with no symptoms at all. But more often, there are various symptoms that may be warning signs of the disease.

Many people with cancer feel sad. They feel a sense of loss of their health, and the life they had before they learned they had the disease. Even when you're done with treatment, you may still feel sad. This is a common response to any serious illness.

It's because of this location, surrounded and obscured by internal organs, that pancreatic tumors are impossible to see or feel during a routine medical exam. Making diagnosis even more difficult is the fact that in its early stages, pancreatic cancer is usually a so-called “silent” disease and causes no symptoms.

Cancer May Grow Undetected for a Decade or More.

Stage 4 Cancer Symptoms

1 In some cases, there are no symptoms at all, so it's possible to have stage 4 cancer and not know it. Most of the time, a cancer that reaches stage 4 affects not only the part of the body where it originated but the areas where it has spread to as well.

Most blood tests aren't used on their own to diagnose cancer. But they can provide clues that may lead your health care team to make the diagnosis. For most types of cancer, a procedure to remove a sample of cells for testing is often needed to be sure.

What is considered catching cancer early? ›

Many types of cancer can be detected at an early stage, when they have just started to form and have yet to spread to other parts of the body. Early detection can be critical, because cancer can often be more successfully treated in its initial stages than when it has grown and metastasized.

Screening: CT is sometimes used to screen for different types of cancer, such as lung and colorectal cancer. Diagnosis: Your doctor may order a CT scan to locate and size suspected tumors. It also may help determine whether a tumor has recurred.

Immunophenotyping. This laboratory test can detect specific cancer cells based on the types of antigens or proteins on the surface of the cells. Immunophenotyping is used to help diagnose specific types of leukemia and lymphoma.

Lumps or skin thickening on breasts or armpits. Skin changes such as a rash, dimpled skin or skin reddening. Changes to your nipples such as dryness, leaking or inverted nipples.

Diagnostic procedures for cancer may include imaging, laboratory tests (including tests for tumor markers), tumor biopsy, endoscopic examination, surgery, or genetic testing.

Which is a symptom that is typical people who have cancer? ›

Radicular pain is nerve pain, which occurs when the cancer is pushing on a nerve in the spine. It can feel like an electric shock going down a limb or around the chest. Sciatica is the most well-known type. Radicular pain can be relieved by treating the tumor to stop it from compressing the nerve causing the pain.

Fatigue may develop as a symptom of blood cancers, such as leukemia, lymphoma and multiple myeloma, because these cancers start in the bone marrow, which produces red blood cells that carry oxygen throughout the body.

Dehydration is a common side effect of cancer treatment. Chemotherapy and radiation treatment can cause dehydration due to other side effects, like fevers, vomiting, diarrhea or excessive urination. These treatments can increase the need for IV hydration due to increased fluid needs.

Types of back pain that could mean cancer

back pain that doesn't seem to be related to movement or doesn't get worse with movement. back pain that usually occurs at night or early in the morning and goes away or gets better during the day. back pain that persists even after physical therapy or other treatments.

Even when stress appears to be linked to cancer risk, the relationship could be indirect. For example, people under chronic stress may develop certain unhealthy behaviors, such as smoking, overeating, becoming less active, or drinking alcohol, that are themselves associated with increased risks of some cancers.

What are the most curable cancers? Although there are no curable cancers, melanoma, Hodgkin lymphoma, and breast, prostate, testicular, cervical, and thyroid cancer have some of the highest 5-year relative survival rates.

Which Type of Cancer Spreads the Fastest? The fastest-moving cancers are pancreatic, brain, esophageal, liver, and skin. Pancreatic cancer is one of the most dangerous types of cancer because it's fast-moving and there's no method of early detection.

The Fastest Killing Cancer

If defining "fastest-killing" cancer is based on which cancer has the worst 5-year relative survival rate, then it would be a tie between pancreatic cancer and malignant mesothelioma (a relatively rare cancer in the U.S. with about 3,000 cases a year).

Lung & Bronchus

Lung and bronchial cancer causes more deaths in the U.S. than any other type of cancer in both men and women. Although survival rates have increased over the years due to improved treatments, the outlook is still bleak. The five-year survival rate is only 22%.

Bone cancer is one of the most painful cancers. Factors that drive bone cancer pain evolve and change with disease progression, according to Patrick Mantyh, PhD, symposium speaker and professor of pharmacology, University of Arizona.

The LSCT was set up by a group of charities all aiming to double survival rates of the six less survivable cancers by 2029. These are stomach, oesophageal, pancreatic, liver, brain & lung cancer, with an average five-year survival rate of just 16%.

A need to sleep much of the time, often spending most of the day in bed or resting.
