Cancer symptoms can sometimes be subtle and may resemble common everyday health problems. Fatigue, digestive discomfort, changes in appetite, or skin changes can have many different causes, which is why they are often overlooked.

Having one of these symptoms does not mean that you have cancer. However, a new, persistent, unexplained, or worsening change in your health deserves attention and may be worth discussing with a healthcare professional.

Here are 15 potential warning signs women should know about.

1. Unexplained Weight Loss

Losing weight without intentionally changing your diet or physical activity can happen for many reasons, including stress, digestive problems, thyroid conditions, medication effects, and other health issues.

However, significant or ongoing unexplained weight loss should be discussed with a healthcare professional, especially when it occurs alongside other unusual symptoms.

2. Persistent or Unusual Fatigue

Feeling tired occasionally is normal. Persistent fatigue that does not improve with adequate rest, however, may deserve further attention.

Fatigue can be associated with many conditions, including anemia, sleep problems, infections, nutritional deficiencies, hormonal issues, and other medical conditions. In some cases, persistent fatigue can also occur alongside cancer.

3. Persistent Bloating

Occasional bloating is common and can be related to diet, digestive problems, or other everyday factors.

Bloating that becomes frequent or persistent, particularly when accompanied by abdominal discomfort, changes in appetite, or feeling full unusually quickly, should be discussed with a healthcare professional.

Persistent bloating has many possible causes and does not automatically indicate cancer.

4. Changes in Skin or Moles

Changes in the appearance of your skin or moles are worth paying attention to.

A spot that changes in size, shape, color, or appearance may need professional evaluation. Other changes to discuss with a healthcare professional include a sore that does not heal, unusual skin growths, persistent scaling, or unexplained changes in skin color.

The ABCDE approach can help you notice some changes in moles:

• A — Asymmetry: One half looks different from the other.
• B — Border: The edges appear irregular or uneven.
• C — Color: The color varies or changes.
• D — Diameter: The spot becomes larger, although concerning changes can occur at smaller sizes.
• E — Evolving: The spot changes over time.

5. Unusual Vaginal or Other Pelvic Changes

Unusual changes involving the pelvic area should not simply be ignored.

Persistent pelvic discomfort, unusual discharge, unexplained changes, or symptoms that are different from your normal pattern can have many causes. If a change continues or becomes more noticeable, consider discussing it with a healthcare professional.

6. Breast Changes Beyond a Lump

A breast lump is not the only change worth noticing.

Other changes can include:

• New dimpling or puckering of the skin
• A persistent change in breast shape or size
• A newly inverted nipple
• Unusual nipple discharge
• Persistent redness or scaling
• A noticeable change in the appearance of one breast

Most breast changes are not caused by cancer, but a new or persistent change should be evaluated.

7. Persistent Indigestion or Heartburn

Occasional indigestion and heartburn are common and can result from diet, acid reflux, medications, or other digestive conditions.

Persistent or worsening symptoms should be discussed with a healthcare professional, especially if they occur together with difficulty swallowing, persistent abdominal discomfort, vomiting, or unexplained weight loss.

These symptoms have many possible causes and do not necessarily indicate cancer.

8. Difficulty Swallowing

Difficulty swallowing, known medically as dysphagia, can have several causes.

Some people may feel as though food is sticking in the throat or chest, while others may experience discomfort when swallowing.

If swallowing difficulties persist, worsen, or interfere with eating and drinking, seek medical evaluation to determine the underlying cause.

9. A Persistent Cough or Hoarseness

A cough can remain for some time after an infection, while allergies, asthma, acid reflux, and other conditions can also cause prolonged coughing.

A persistent cough or unexplained hoarseness that does not improve should be evaluated, particularly if accompanied by breathing difficulties, chest discomfort, coughing up blood, or unexplained weight loss.

Persistent respiratory symptoms have many possible causes and should not automatically be assumed to be cancer.

10. Persistent Pelvic or Abdominal Pain

Occasional abdominal discomfort can happen for many harmless reasons.

However, persistent or unexplained pain, pressure, or fullness in the abdomen or pelvic area deserves attention, particularly when it continues or interferes with normal activities.

Digestive, urinary, reproductive, and other health conditions can cause similar symptoms, so professional evaluation is important when symptoms persist.

11. Persistent Mouth Changes

Mouth irritation and sores are common and often resolve without treatment.

A sore, lump, thickened area, or unusual red or white patch that persists or fails to heal should be examined by a dentist or healthcare professional.

Persistent mouth changes can have many causes, including irritation, infection, nutritional issues, and other medical conditions.

12. Changes in Bowel Habits

Temporary changes in bowel habits are common.

However, persistent changes such as ongoing constipation, diarrhea, changes in stool appearance, a continuing feeling of incomplete bowel movements, or blood in the stool should be discussed with a healthcare professional.

These symptoms can result from many conditions and do not automatically indicate colorectal cancer.

13. Persistent Night Sweats or Unexplained Fever

Night sweats and fever are often associated with infections and other common health conditions.

Repeated episodes without an obvious explanation, particularly when accompanied by other persistent symptoms, should be discussed with a healthcare professional.

14. Persistent Swollen Lymph Nodes

Lymph nodes can become temporarily enlarged when the immune system responds to an infection.

A swollen lymph node that persists, continues to grow, feels unusually firm, or appears without an obvious explanation should be evaluated.

The characteristics and location of the swelling, along with other symptoms, can help a healthcare professional determine whether additional testing is appropriate.

15. Changes Under the Nails

Changes beneath the fingernails or toenails can have many explanations, including minor injuries, infections, medications, or other conditions.

A new or changing dark streak or unusual pigmentation that does not appear to be growing out with the nail should be evaluated by a healthcare professional.

Although uncommon, certain persistent nail changes can be associated with skin conditions that require medical assessment.

When Should You Talk to a Doctor?

Having one or more of these symptoms does not mean that you have cancer. Many of the symptoms discussed above are much more commonly caused by non-cancerous conditions.

The most important factors are whether a symptom is new, persistent, worsening, unexplained, or unusual for you.

If a concerning symptom continues for several weeks, repeatedly returns, becomes more severe, or interferes with your normal activities, consider contacting a qualified healthcare professional.

Do not attempt to diagnose yourself based on a list of symptoms found online. A healthcare professional can review your medical history, perform an appropriate examination, and recommend testing when necessary.

Final Thoughts

Being aware of potential warning signs can help you notice changes in your health, but symptoms alone cannot determine whether someone has cancer.

Many common symptoms have several possible explanations, and most are not caused by cancer. The safest approach is to pay attention to persistent or unusual changes and discuss them with a qualified healthcare professional when appropriate.
