A spiculated mass is a cluster of barbed tissue that is one of the primary indicators of cancer. Rather than a smooth lump, it has spicules or thin, elongated pieces of tissue sticking out from its perimeter. These spiky tumors can appear anywhere inside the body, but are often found in the breasts or lungs. When found, these masses are typically biopsied to confirm whether they are malignant or benign. If cancerous, treatment ranging from excision to radiation can be used.

Of all the indications of cancer, which include calcified tissue, lesions and smooth masses, the spiculated mass is believed to have the highest incidence of malignancy. For breast cancer cases, one explanation for this might be that cell tissue in these masses has abnormally higher levels of progesterone and estrogen. Some studies have shown that a spiculated mass typically has at least 30 percent more progesterone receptors and estrogen receptors than normal breast tissue or non-spiculated lumps.

While usually cancerous, it is possible in rare cases for a spiculated mass to be benign, particularly in instances where there is scar tissue, granular tumors or the presence of foreign matter in the body. When present, these masses can appear singly or in multiples. Often, they occur with adjacent calcified tissue.


In cases of breast cancer, a spiculated mass usually exists on the periphery of the breast, not the center, and is typically discovered through ultrasonography or a mammogram, which is a screening that uses radiation to create images of breast tissue. A radiologist is able to use computer-aided diagnosis (CAD) software to magnify and highlight abnormalities in breast images with colored lines in order to evaluate whether a mass is spiculated. Spicules are difficult to discern. For lung cancer cases, a computerized tomography (CT) chest scan or magnetic resonance imaging (MRI) can detect a spiculated mass. In conjunction with those procedures, an invasive surgical screening of the chest known as mediastinoscopy might be used.

No other symptoms may accompany the presence of spiculated masses. Sometimes, however, pain, skin thickening and infection can be present. For some breast cancer patients, the inversion of nipples may accompany the presence of a mass of this kind. Smokers and people with cancer history in their families have a higher risk of suffering from spiculated masses.

Treatment for this type of mass located in the breast often includes lumpectomy or mastectomy. Radiotherapy and chemotherapy can be used for both breast and lung masses. Doctors often recommend lifestyle alterations, as well, such as abstinence from alcohol and smoking.

My only son (43) was diagnosed with granulosis of the right lower lobe. thankful it is not cancer,but his wife continues to smoke around him. A biopsy was performed and the doctor stated "this is as good as your lungs will get." What is the outcome? Will the pain and symptoms of tiredness decrease? They have a family of small children and no insurance. His primary doctor is great, never pressures for all payments. Just what they can afford. God bless doctors who still heal first. Any insight to this and the progress to expect?

@feasting – My doctor told me that I will need to start getting mammograms when I'm forty. She said that before then, my breast tissue will be too dense for the scan to be useful.

Since it would be hard for anyone to see a spiculated mass on a mammogram of a thirty-year-old, there is an alternative. You can get an ultrasound of your breasts.

You probably only need to do this if you feel a lump or soreness, though. I doubt a doctor would recommend it for no reason.

Breast cancer runs in my family. My grandmother died of it, and I recall the dread that I felt when I heard that the doctor had found a spiculated mass in her breast.

She had a masectomy, but that wasn't enough. She died anyway, and she left me with the fear that I might have the gene for this.

I'm only thirty-three right now, and I'm wondering if I should go ahead and start having mammograms. My doctor hasn't recommended that I get one yet, but I feel like it might be a good idea.

I worry a lot about my sister one day getting a spiculated mass in her lungs. She has been smoking for the past twenty-five years, and she has never even tried to quit.

She once told me that her philosophy is, “We've all got to go some way.” I think that she would change her outlook if her doctor told her that he had found a cancerous mass on her lungs, though.

I can't imagine how scary it would be to hear that. I just keep praying that she will quit smoking one day, and I hope that it won't be too late.
