How to Recognize Sneaky Cancer Symptoms — Looking at Cancers That Are Most Often Misdiagnosed

Lymphoma, a type of blood cancer, is one that often creeps in silently, without symptoms. Even when symptoms do present early on, they don’t typically indicate cancer. For example, swollen glands are much more likely to be from an upper respiratory infection than lymphoma — so a person may not seek medical attention.

If you are at risk for this cancer because you had cancer or an organ transplant in the past, you have an autoimmune disease, or you have an infection such as HIV or Epstein-Barr, it may be worth watching out for symptoms like these:

• Swollen lymph nodes in your neck, armpits, or groin
• Weight loss
• Tiredness
• Fevers
• Swollen belly

But keep in mind that these are more likely to be symptoms of something far less serious, such as a run-of-the-mill infection. There are also a group of symptoms doctors refer to as "B symptoms." Those include a fever, night sweats, or weight loss.

"If people are having any of these symptoms, it's really important that they tell their physician early so that the proper testing can be done,” Dr. Elise Chong, medical oncologist at Penn Medicine, previously told SurvivorNet.

Ovarian Cancer

Ovarian cancer is often referred to as the "cancer that whispers," according to Dr. Beth Karlan, Director of the Women's Cancer Program at the Cedars-Sinai Medical Center. It has symptoms that are very vague and are often similar to the symptoms many women experience every month with their menstrual cycle.

However, women who experience any of the following symptoms and notice they appear to be getting worse should mention this to a doctor so next steps can be taken if they are needed.

Symptoms to be aware of include:

• Feeling full earlier/decrease in appetite
• Feeling bloated
• Changes in bowel habits
• Pain in the pelvis
• Urinary symptoms, such as an urgent need to go
• Extreme fatigue
• Abdominal swelling
• Pain during sex

It's hard to connect these symptoms specifically with the ovaries because they could be caused by a whole host of other issues. That's why Dr. Karlan, as well as many other top gynecologic oncologists in the U.S., urge women to be vigilant about getting tested if they feel that something is amiss with their bodies.

Lung Cancer

Lung cancer is notoriously difficult to catch in the early stages and is often diagnosed when it has progressed to an advanced cancer and spread to other parts of the body. Your doctor may suspect lung cancer after seeing a shadow on a routine chest X-ray that requires further evaluation. In some instances, vague symptoms may be present, such as:

• A cough that doesn't go away, that gets worse, or that brings up bloody phlegm
• Shortness of breath
• Fatigue
• Chest pain
• Hoarse voice
• Appetite loss
• Weight loss

Any of these symptoms may indicate lung cancer and should be mentioned to your doctor, particularly if you are at risk for the disease. While lung cancer screening isn’t recommended widely for the general population like mammograms or skin cancer evaluations, there are specific groups of people who should be screened, according to experts. This includes people who are or were heavy smokers (smoked the equivalent of a pack a day for 20 years or more), currently smoke now or quit within the last 15 years, and are between the ages of 55 and 80.

The main takeaway here is that there are several different types of cancer that don’t present symptoms until later stages. This is why it’s so important to be aware of your body and inform doctors about any changes, however minor they may seem, so that you can consider next steps together.
