请教B超可以诊断出卵巢囊肿和卵巢癌的区别吗？

九个月前查出两边卵巢囊肿，右边5.5x2.8x3.1cm,左边3.1x2.7x2.6cm, 上星期复查，右边沒有变化，左边长大到4.6x3.8x4.7cm.由于医生这星期休假，所以还不知后面是否还有什么检查

由于现在沒任何疼痛症状，只有月中时有些涨，上网查说超过5cm应该算肿瘤，有可能会变成卵巢癌。请问我应该手术吗？5cm以上自行消失应该不大可能对吗？先谢谢大家了

检查结果如下，

Findings:

The uterus is retroflexed and measures approximately 9.4 x 4.6 x

5.2 cm. Endometrium measures 6 mm in thickness and appears

normal. 1.1 cm right anterior mid intramural fibroid. 1.1 cm left

fundal subserosal fibroid. The right ovary measures 5.6 x 3.1 x

3.1 cm, unchanged. Normal follicles up the periphery. A bilobed

lesion with low-level echoes measures 5 x 2.5 x 3 cm. The left

ovary measures 5.5 x 4 x 5.3 cm and contains a 4.6 x 3.8 x 4.7 cm

unilocular cyst with low-level echoes, increased. Small amount of

normal surrounding ovarian tissue. No free fluid or

hydronephrosis.

 

 

IMPRESSION:

1. The left ovarian cystic lesion compatible with endometrioma

has enlarged mildly. The bilobed lesion in the right ovary has

not changed significantly.

2. Endometrium appears normal with interval removal of an

endometrial polyp.

3. 2 small discrete uterine fibroids.
