Does a lump in the testicle always mean cancer?

No, the appearance of a lump in the testicle does not always mean you have cancer. Although a lump requires medical attention, the causes may range from various conditions; some testicular tumors (especially in children) may be benign, while in other cases, tumors may be malignant (cancerous) [3]. Since self-diagnosis is not possible, visiting a doctor is essential to accurately evaluate any swelling or change in the texture of the testicle [1].

Symptoms requiring medical examination

It is important not to ignore any changes that occur in the testicle. Symptoms associated with testicular cancer may include a painless lump or swelling in either testicle, a noticeable change in how the testicle feels, or a feeling of heaviness or mild pain in the lower abdomen or groin (where the thigh meets the abdomen). Some patients may also notice a sudden buildup of fluid within the scrotum or discomfort in that area [1]. In rare cases in children, symptoms may include early signs of puberty or breast enlargement, which warrants immediate medical consultation [3].

How are testicular lumps diagnosed?

To determine the nature of the lump, doctors rely on a series of diagnostic procedures. Diagnosis does not rely on physical examination alone, but often includes the following:

• Clinical examination: The doctor will carefully examine the testicle and scrotum to evaluate the lump [1].
• Ultrasound: This is a primary method for accurately imaging testicular tissue and determining the nature of the lump [1].
• Blood tests: A test for tumor markers such as Alpha-fetoprotein (AFP) may be ordered; elevated levels of this protein in the blood may indicate the presence of germ cell tumors in the testicle [2]. However, it should be noted that normal levels of this marker in the blood do not completely rule out the possibility of cancer, as some tumors do not produce high levels of this protein [2].
• Surgical diagnosis: In cases with a strong suspicion of cancer, a complete removal of the testicle (inguinal orchiectomy) may be performed to examine the tissue under a microscope and confirm the diagnosis accurately, which is the standard procedure to determine the presence of cancer cells [1].

Steps for dealing with a lump

If you notice a lump, do not try to diagnose yourself. Go to a doctor, who may also request additional tests such as a CT scan or MRI to evaluate the condition. Remember that testicular cancer is often successfully treated when detected early through surgery, chemotherapy, or radiation, based on the recommendations of the specialized medical team [1].
