What are the main causes of varicose veins and spider veins?

Varicose veins and spider veins develop when valves in the veins become weakened or damaged, causing blood to pool. Common causes include genetics (family history), aging, pregnancy, prolonged standing or sitting, obesity, and hormonal changes. Women are more susceptible due to hormonal fluctuations during pregnancy, menopause, or from birth control use.

How do I know if I need treatment for my varicose veins?

You should consider treatment if you experience symptoms such as leg pain, aching, heaviness, swelling, cramping, restless legs, skin discoloration, or itching around the veins. Even without symptoms, large or bulging varicose veins may benefit from treatment to prevent complications. A consultation with Dr. Figueroa at VeinCentre can determine if treatment is right for you.

What is sclerotherapy and how does it work?

Sclerotherapy is a minimally invasive treatment where a specialized solution is injected directly into spider veins or small varicose veins. This solution irritates the vein walls, causing them to collapse and seal shut. Blood is then rerouted through healthier veins, and the treated vein is gradually absorbed by the body over several weeks. It's highly effective with a 90%+ success rate.

Are varicose vein treatments covered by OHIP?

Yes, consultations at VeinCentre are OHIP-covered. Treatment coverage depends on medical necessity. If your varicose veins cause symptoms like pain, swelling, or skin changes, treatments like radiofrequency ablation or VenaSeal may be covered by OHIP. Cosmetic treatments for spider veins are typically not covered. Dr. Figueroa will assess your condition and discuss coverage options during your consultation.

How long does a typical vein treatment appointment take?

Treatment duration varies by procedure type. Sclerotherapy typically takes 30-45 minutes, VenaSeal Glue Ablation takes 30-45 minutes, and Radiofrequency Ablation (RFA) takes 45-60 minutes. These are outpatient procedures performed in our Toronto or Richmond Hill clinics, allowing you to return home the same day.

Is vein treatment painful?

Modern vein treatments are minimally invasive and well-tolerated. Local anesthesia is used to numb the treatment area, so you'll feel minimal discomfort during the procedure. Most patients describe feeling only slight pressure or mild sensations. Sclerotherapy involves small needle injections that feel like tiny pinches. Post-treatment discomfort is typically mild and manageable with over-the-counter pain relief.

What is the recovery time after vein treatment?

Recovery is quick with modern vein treatments. Sclerotherapy and VenaSeal allow immediate return to normal activities with no compression stockings required after VenaSeal. Radiofrequency Ablation typically requires 1-2 days before returning to work and wearing compression stockings for 1-2 weeks. Walking is encouraged immediately after all procedures to promote healing. Most patients resume regular activities within days.

Can varicose veins come back after treatment?

Treated veins do not reopen once successfully closed. However, new varicose veins can develop in other areas over time due to ongoing genetic factors, aging, or lifestyle conditions. The recurrence rate is low with modern treatments—RFA and VenaSeal have 95%+ success rates. Maintaining a healthy weight, staying active, and wearing compression stockings when needed can help prevent new vein problems.

How many treatment sessions will I need?

The number of sessions depends on the severity and extent of your vein condition. Many patients see significant improvement after just one treatment session. Spider veins may require 2-3 sclerotherapy sessions spaced several weeks apart for optimal results. Larger varicose veins treated with RFA or VenaSeal typically require only one session per vein. Dr. Figueroa will create a personalized treatment plan during your consultation.

What should I expect during my first consultation?

During your OHIP-covered consultation at VeinCentre, Dr. Figueroa will review your medical history, examine your legs, and may perform an ultrasound to assess vein health and blood flow. You'll discuss your symptoms, treatment goals, and concerns. Dr. Figueroa will explain which treatment options are best suited for your condition—whether sclerotherapy, radiofrequency ablation, or VenaSeal—and answer all your questions about the procedure, recovery, and expected results.

Visible Veins on Breasts During Pregnancy: What to Expect and When to Worry

Oct 8, 2025

Updated: Oct 23

Noticing a web-like network of blue or green veins across your breasts, upper chest, or décolletage during pregnancy can be surprising. For many women this is one of the early visible changes of pregnancy, and in most cases it is a normal response to the changes happening in the body. Still, it is natural to wonder why the veins appear, whether they will fade after pregnancy and breastfeeding, and when they might point to something that needs a medical check.

This guide, prepared by the team at VeinCentre under the direction of Dr. Luis Figueroa, a vascular surgeon, explains why veins become more visible on the breasts during pregnancy, what the changes usually look like over time, other reasons breast veins can show, warning signs, comfort tips, and the options that may be considered after pregnancy and breastfeeding. It is general information and does not replace an exam by your own doctor or midwife.

Why Do Veins Become Visible on the Breasts During Pregnancy?

Pregnancy brings large changes to the circulation and to hormones. Several of them work together to make the veins under the skin of the chest easier to see.

More Blood Volume

During pregnancy the amount of blood in the body increases to support the baby and the placenta. To carry that extra volume, blood vessels throughout the body widen, including the veins in the breasts.

Hormonal Changes

Rising levels of estrogen and progesterone relax the muscle in the walls of blood vessels. Relaxed veins can stretch and hold more blood, and they sit closer to the surface of the skin.

Preparing for Breastfeeding

The breasts change early in pregnancy to get ready to produce milk. The breast tissue grows and needs more blood flow, and the surface veins expand to drain it.

Stretching and Thinner Skin

As the breasts grow, the skin over them stretches and becomes thinner. Because the skin of the chest has little fat under it, veins that were hidden before can now show through. They look blue or green because of how light passes through skin.

What Changes to Expect During and After Pregnancy

Every body is different, so the timing varies. The table below gives a general picture of how breast changes and visible veins often progress.

Stage	What you may notice	What is going on
First trimester	A blue network of veins on the breasts and chest, along with breast tenderness or tingling	Hormones rise and the breast tissue begins to change
Second trimester	Veins may look darker and more prominent, and the areolas may darken	Blood volume continues to increase
Third trimester	Veins may look more prominent, and the skin may be stretched	The breasts continue to prepare for feeding
Breastfeeding	Veins often stay visible, and may look fuller when the breasts are full of milk	Blood flow to the breasts stays high while you nurse
After weaning	In many women, the veins gradually become less noticeable	Hormones and blood flow settle back toward their usual levels

How quickly the veins fade after breastfeeding varies. In some women they become much less visible, and in others a few veins remain noticeable.

Other Reasons Breast Veins Can Be Visible

Pregnancy is a common reason, but it is not the only one. Prominent veins on the chest can also be seen in people who are not pregnant, including men.

Fair, thin skin or low body fat: With less pigment and less fat covering the veins, they are easier to see. This is common in athletes too.
Breast implants: Implants can stretch the skin over the breast so that veins show more.
Weight loss: Losing weight can reduce the layer of fat that hides the veins.
Hormonal changes: Starting or changing birth control, fertility medication, or hormone therapy can cause breast tenderness and mild changes in veins.
Genetics: Some people simply have more visible veins, and it runs in families.

When Are Visible Breast Veins a Concern?

In most cases visible breast veins are harmless. Some signs, however, mean you should talk to a doctor. The table below is a guide, and it does not replace an assessment.

What you notice	What it may mean	What to do
Painless blue veins on both breasts during pregnancy	Often a normal response to pregnancy	Mention it at a prenatal visit if you have questions
Veins that appear suddenly on one breast only	Needs to be looked at	Book an exam with your doctor
A hard, tender, red, cord-like vein with warmth	May be an inflamed or clotted surface vein	See a doctor promptly
Veins together with a lump, skin dimpling, nipple changes, or discharge	Needs to be looked at right away	See your doctor or a breast specialist promptly
Swelling of the face, neck, or arm with enlarged chest veins, or trouble breathing	Could be a serious problem	Go to an emergency department

A Tender, Cord-Like Vein on the Breast or Chest Wall

Sometimes a surface vein on the breast or the side of the chest wall becomes inflamed and a small clot forms. It can feel like a tender, rope-like cord under the skin, and it may pull tight when you raise your arm. This should be checked by a doctor, who can confirm what it is and advise on treatment.

Questions You Can Bring to a Prenatal Visit

Are the veins on my breasts what you would expect at this stage of my pregnancy?
Is the change on one side only, or on both sides?
Are there any new lumps, areas of pain, or skin changes that I should have examined?
Is there anything I should do or avoid while I am pregnant or nursing?

Comfort Tips During Pregnancy

Vein treatments are not done during pregnancy, so the focus is on comfort. Many women find these steps helpful:

Wear a supportive bra: A soft, well-fitting maternity bra with wide straps can feel better than a tight or rigid one.
Use a cool compress: If your breasts feel warm or full, a cool, damp cloth for a short time can be soothing.
Moisturize your skin: Keeping skin hydrated with a gentle, fragrance-free moisturizer can help with the stretching feeling.
Prop yourself up at night: If your chest feels heavy when you lie flat, an extra pillow may help.

Ask your doctor or midwife before using any new product on your skin during pregnancy or breastfeeding.

Options After Pregnancy and Breastfeeding

For many women, breast veins become less noticeable after pregnancy and weaning. If some veins remain visible and bother you, you can have them assessed. A treatment is generally considered only once you are no longer pregnant or breastfeeding, and your doctor will advise on timing.

Sclerotherapy for Chest and Breast Veins

Sclerotherapy is a procedure in which a medical solution is injected into small visible veins with a fine needle. The solution irritates the lining of the vein so that it closes, and over time the body absorbs it. At VeinCentre, sclerotherapy is priced at $300 plus HST per session, or 3 sessions for $750 plus HST. The number of sessions needed depends on the veins being treated, and results vary from person to person.

Consultation First

Before any treatment, a consultation lets the doctor look at your veins, review your history, and explain which options, if any, make sense for you. Your consultation and Duplex ultrasound at VeinCentre are covered by OHIP for eligible patients, and no referral is needed to book. If cost is a concern, VeinCentre offers Medicard financing through iFinance Canada, with payments from $22 per week over 12 to 72 months, no down payment, and no penalty for early payment.

Frequently Asked Questions

Will my breast veins go away after I stop breastfeeding?

In many women they become less noticeable as hormones and blood flow return toward usual levels, but this varies. If veins stay visible and bother you, you can have them assessed.

Can I have breast veins treated if I plan to have more children?

You can ask about it at a consultation. Because a future pregnancy can bring new visible veins, some women prefer to wait until they are done having children. Your doctor can talk through the timing with you.

Is it safe to treat breast veins while pregnant or nursing?

Elective vein treatments are not done during pregnancy or breastfeeding. Your doctor will advise you on when it would be appropriate.

Can breastfeeding leave veins more visible on the chest?

Some women, especially those with a family history of visible veins, may notice that a few veins stay more visible afterward. This does not mean anything is wrong.

Do I need a referral to be assessed?

No. You can book directly with VeinCentre by calling (289) 809-1333.
